Is It Better To Use China Steel For Metal Roofing Than Other Materials?

Investing in your home is one of the most important decisions you need to focus on and make sure that you do it right. This does not only include the lot and the entirety of your house, but even the most simple and basic parts of your home. You don’t want your home to always be leaking, so you want to choose the best materials for your pipes and most especially, your roof. There are a lot of roofing materials you can choose from but one of the most preferred is China steel.

There are different kinds of steels to choose from, which can be quite confusing to differentiate. And this is even worse if you don’t have any idea what each kind of steel can benefit you. Here are other types of steel:

  • Stainless steel

Compared to the normal kind of steel, the stainless kind is better since it is less susceptible to rust which means it doesn’t need additional coating. But because of this rare property, it is more expensive compared not only to other types of steel, but to most metal roofing materials in general. It will be the best option for you if you don’t want to do an additional coating task.

Made from the combination of alloyed steel and zinc, this kind of steel is very sturdy especially, if you will take care of it well. And using this type of China steel for your roof is a great option if you want your investment to last.

What Makes Using China Steel Better than Others

In the U.S., most people prefer to use China steel. There are a lot of benefits that using this type of metal roofing can provide you, which is why it was able to build its immense popularity.

 1. Cost-effective than other materials

China steel cost less than most materials that are usedfor roofing. You can choose this for your roofing especially, if your budget is limited and you are only starting up on your home and investment.

 2. Lightweight to Use

Compared to other materials, this is the most lightweight material of all. For instance, a sq. ft. of a tile can weigh 9 lbs. but it only weighs 1.5 lbs. if it is China steel.

 3. Stress-free to Install

This type of steel is very stress-free to install primarily because of how light it weighs. You can do the installment yourself and you wouldn’t need to pay for the service of the experts. You only need to remove the previous China steel installed, clean the surface then install the new one.

 4.Best for Your Safety

This steel is best if your priority is safety primarily because it is fire resistant. With this, you can be assured that your family won’t be in danger in case of fiery accidents.

5. Maintenance Costs Low

6. Lasts longer than Other Metal Roofing Materials

One Big Disadvantage About China Steel

The only disadvantage for the common type of China steel is its vulnerability to corrosion and rusting. While there are those special kinds of steel that are less susceptible than the common one, it is always exposed to rust-causing conditions. But don’t worry, you can do something about them to prevent them from rusting.

Using a special plastic coating on China steel is enough to prevent it from corroding and rusting. You can use a zinc coating combined with a sealant and paint to make the protection more effective.

Other Metal Roofing Materials You Can Try

Metal roofs in general, be it China steel or not, are more durable to use than other roofing materials. They are resistant to most outside factors and don’t easily get dented from impact with different materials like tree limbs and snow. They are also mostly cost-effective than other materials for roofs. Besides from China steel, you can also make use of the following metals.

  • Alloys (for More Specific Protection)

There are different kinds of metal alloys that you could use for roofing, especially, if you have certain aspects you need to focus on, such as the durability or the strength of the roof. One big disadvantage of using alloys though, is that they can be very costly.

  • Aluminum

This kind of metal is less vulnerable to rust which is what makes it alluring for customers. It also requires little attention for maintenance, but you need to coat it to have it look more natural.

  • Copper

Very costly and rare as compared to China steel, this old metal roofing material is now used more as an accent than using it as the dominant roof material.

Is it better to use China steel than other metal materials made for roofs? It is, especially since there are different kinds of steel you can choose from to target your specific needs.

The growth of steel industry and the current trend in steel prices

Steel is one of the most important part of almost every industry. Construction of high rise buildings, bridges, metro, roads and factories cannot be imagined without steel. It is used in many forms in the different industries and is a major reinforcement material along with Iron. Steel was invented around 100 years ago. The importance of steel has risen by leaps and bounds due to various reasons and attributes of steel. Steel does not get rusted easily and is light-weight as compared to Iron. It is durable, ductile, malleable, corrosion resistant and fire-resistant among scores of other benefits. All these features of Steel have made it the king of raw materials used in almost every industry.

Steel is mostly used as structural steel which is the most preferred framework material for residential as well as non-residential construction. The steel beams and columns are the skeleton of the building and support the entire construction just like the bones in a body do. Angle bars, I-Beams, H beams, IPE etc. are some of the other structural elements required in the construction. It is therefore clear that steel is indispensable in industries. The growth in the steel industry is a manifestation of this fact. Steel industry across the globe has shown tremendous growth in the past two decades. Government projects involving metro, roads and bridge construction has also fuelled the growth. The growth in the real estate is also linked to the growth in the steel industry. The specially processed steel like galvanized steel has made steel more versatile and fit for various purposes. Some of the commonly used steel products are steel sections, steel pipe, steel tube, steel coil, steel sheet and steel plate. The process of galvanization increases the strength and durability of steel. Steel has several grades and steel prices vary accordingly. Other types of steel are:

  • Galvanized steel
  • Galvalume Steel
  • Prepainted Steel
  • Hot rolled steel
  • Cold rolled steel

The floating steel prices across the globe - A study

Steel prices are not fixed and vary according to the rule of demand and supply. Over the years, the steel prices of reduced considerably and if you have bulk requirement of steel for any purpose, it is the best time to buy. Once the constructions are on in full swing and the recession subsides, the price of steel is likely to skyrocket. The price of steel is also dependent on the grade of steel. Steel can be of different grades depending on its purity and amount of components added to Iron, which is the principle element present in steel. The price of steel also depends on the treatment of steel. For instance, normal steel and galvanized steel have a price difference and so has the Boron added steel equipment. The chromated galvalume steel has a higher price than galvanized steel as it has various advantages in comparison to galvanized steel. Galvalume steel which has the additional property of being anti-fingerprint is priced higher than any other form of steel. Similarly, cold rolled, hot rolled and pre-painted steel also have different prices. Steel prices also vary country to country. There are many countries which produce a lot of iron ore and such countries are able to make their own steel and therefore in the local market, the price of steel is less. However, when the same steel is exported to other countries, the price increases manifold.

Multiple factors come together to control and change the prices of steel globally

The freight charges, custom duty and other taxes are added on to it. The commonly used Steel products that are used for various purposes like construction of bridges, buildings and automobiles, etc. are steel sheets, plates, coils and wires. As they have high tensile strength they are also used for making cables of lifts that are used to carry heavy load. For example, the wires of lift in colliery are made of steel. These wires are used to pull coal and the miners out of the mines. As this requires strength, steel is invariably used for this purpose. All the skyscrapers and high-rise buildings that we see around us cannot stand without the strong support of steel.

  • The steel industry is an evergreen industry as use of steel cannot stop.
  • The steel prices vary from country to country and quality to quality.


Ensure strong and durable construction with structural steel and angle iron

Iron and steel are integral elements in every construction which provides strength to the construction and make it capable of tolerating extreme weather and destructive forces of nature. They must be of supreme quality as the quality of construction must never be compromised as when natural calamities strike, it is the homes that provide shelter. Structural steel and angle irons are two of the most important reinforcement required in every construction. They are used in building beams, pillars and the roof, which has to sustain the load of the entire construction. Steel holds so much importance owing to its features like strength to weight ratio, flexibility and being rust free. After 100 years of its invention, no construction can be fathomed without steel. Whether it is a high rise building, war ships or long pipelines, steel is in every such thing.

  • Structural steel is a framework material used in all the non-residential homes.
  • Beams and columns made of steel are the skeleton of the building which supports the entire structure.
  • Heavy angle iron is used as a structural element in bridges and buildings.

Structural Steel: Framework of every high-rise construction

Skyscrapers and high rise buildings that we see around us does not only require brick and mortar. Structural steel is the most important element that renders the desired strength to it. It is in fact the framework which holds the entire construction and protects it from the brute forces of nature. Beams and columns are the steel members that support every part of the building. The steel elements that are required in every constructions can be categorized under steel sections, steel pipes, steel tubes, steel coils, steel sheets and steel plates. The steel sections include a wide range of mild steel products such as Angle Iron, flat bar, I-beam, H-beam, IPE and steel channels. Angle irons have a variety of applications such as engineering structures, building structures and also metal components and frameworks of factories. The transmission towers and signal towers also use angle iron in its construction.

Another structural steel, flat bars are also an important element used for fabrication, structuring and building frames. These bars are made of mild steel and hence can be easily cut, drilled and welded. They are primarily used in making furniture, machinery, spare parts of the railways and ships, towers, boilers and similar structures. The characteristics of flat bars also make it useful in making pipes, roles and thin slabs. The plasticity of the flat bar lets it handle larger pull. I-beam crossed section comprises Universal beam and universal columns, IPE and H-beam. The elements that are horizontal elements that are made of structural steel and find use civil engineering works like bridges. H-beam is a structural steel of cross sectional shape of H-section steel. It is used in various types of constructions like high-rise building and factories, etc. These beams have excellent bending capabilities which makes for simple and cost-effective construction. The European I - beam is called IPE having parallel flange surface. These are available in various sizes and find application in construction industries. They can be used both as columns and beams with composite materials like concrete. IPE is a section of long steel. It has architectural and mechanical applications like bridges, buildings, automobiles, etc.

The many utilities of structural steel and angle steel

Another important structural steel is the steel channel with a U-shaped cross section with right angles having two narrow sides. Manufacturing and fabricating a wide range of engineering products. It is a cross section of a slot line of steel. The steel channels are of two types- common steel channels and light steel channels. They are used for various purposes, including building structures, vehicles and other industrial structures. These channels are often used in combination with the H-Beam. All these structural steels play a pivotal role in all types of construction. The quality of these elements is therefore very important. Every construction projects require hundreds of different building materials. The commercial and industrial structures experience heavy foot fall and therefore are built using structural steel and reinforced concrete. While building a structure, it is important to decide the materials which are required to be used. A lot needs to be considered when choosing construction material. Cost is definitely a controlling factor, durability, sustainability, fire resistance, strength are also some of the desired attributes.


Happy Mid-Autumn Festival

The Mid-Autumn Festival is coming we

Wish you and your family happy on this gathering day.

Best wishes from | Sunspeed Group | Sunspeed Group | Sunspeed Group

Please note that we will have a 3-days holiday from Sep.6 2014 to Sep.8 2014.

The Mid-Autumn Festival is an official harvest festival celebrated by Chinese and Vietnamese peoples. The festival is held on the 15th day of the eighth month in the Chinese calendar and Vietnamese calendar, during a full moon, which is in September or early October in the Gregorian calendar, within 15 days to the autumnal equinox.

The Government of the People’s Republic of China listed the festival as an “intangible cultural heritage” in 2006 and a public holiday in 2008. It is also a public holiday in Taiwan. Among the Vietnamese, it is considered the second-most important holiday tradition.

Meanings of the moon cake festival

The festival celebrates three fundamental concepts which are closely tied to one another:

  • Gathering: such as family and friends coming together, or harvesting crops
  • Thanksgiving: to give thanks for the harvest, or for harmonious unions
  • Praying: (asking for conceptual or material satisfaction), such as for babies, a spouse, beauty, longevity, or for a good future

Traditions and myths surrounding the festival are formed around these three concepts, although traditions have changed over time due to changes in technology, science, economy, culture, and religion.

A Story of Mid-Autumn Festival

In the ancient past, there was a hero named [Hou] Yi who was excellent at shooting. His wife was Chang’e. One year, the ten suns rose in the sky together, causing great disaster to people. Yi shot down nine of the suns and left only one to provide light. An immortal admired Yi and sent him the elixir of immortality. Yi did not want to leave Chang’e and be immortal without her, so he let Chang’e keep the elixir. But Feng Meng, one of his apprentices, knew this secret. So, on the fifteenth of August in the lunar calendar, when Yi went hunting, Feng Meng broke into Yi’s house and forced Chang’e to give the elixir to him. Chang’e refused to do so. Instead, she swallowed it and flew into the sky. Since she loved her husband very much and hoped to live nearby, she chose the moon for her residence. When Yi came back and learned what had happened, he felt so sad that he displayed the fruits and cakes Chang’e liked in the yard and gave sacrifices to his wife. People soon learned about these activities, and since they also were sympathetic to Chang’e they participated in these sacrifices with Yi.


Structural Steel

Steel is the most widely used construction material in the world today. Its strength-to-weight ratio, toughness, flexibility, pliability, eco-friendliness, and plain aesthetic appeal have, during the 100-plus years since its invention, proven steel as the essential structural part of practically every substantial commercial structure around the world. From highrises to bridges, automobiles to ships, pipelines to rocket gantries, the sturdiness and flexibility of steel makes the fixtures of modern civilization possible.

Structural steel is the most preferred framework material for non-residential buildings on the globe. Steel members, known as beams and columns, constitute the bone structure of the building supporting all of the other parts of the building.

In the majority of developed countries, the shapes available are set out in published standards, Common structural shapes including:

I-beam (I-shaped cross-section - in the uk these include Universal Beams (UB) and Universal Columns (UC); in Europe it includes the IPE, HE, HL, HD and other sections; in the US it includes Wide Flange (WF) and H sections) also known as H-beam, W-beam (for “wide flange”) Universal Beam (UB) Rolled Steel Joist (RSJ), or double-T (especially inPolish Bulgarian Spanish Italian and German), is a beam with an I- or H-shaped cross-section. The horizontal elements of the “I” are known as flanges, while the vertical element is termed the “web”. I-beams are usually made of structural steel and are used in construction and civil engineering.

HSS-Shape (Hollow structural section also known as SHS (structural hollow section) and including square, rectangular, circular (pipe) and elliptical cross sections)

A hollow structural section is a kind of metal profile having a hollow tubular cross-section. The phrase is used mostly in USA, or some other countries which follow US construction or engineering terminology

HSS members can be circular, square, or rectangular sections, although other shapes are available, such as elliptical. HSS is simply made up of structural steel per code. HSS is usually incorrectly introduced as hollow structural steel. Rectangular and square HSS are also frequently called tube steel or structural tubing. Circular HSS are occasionally wrongly labeled steel pipe while correct steel pipe is actually dimensioned and classed differently from HSS. (HSS measurements are according to exterior size of the profile, while pipes are basically dimensioned based on interior diameters. The corners of HSS are heavily rounded, which has a radius which is approximately twice the wall thickness. The wall thickness is uniform around the section.

Angle Iron(L-shaped cross-section)

An Angle Iron is a flat metal rod that has been folded to a 90-degree angle along its length, resulting in an L-shaped piece. For Equal Angles the two sides of the angle are of equal length, with unequal length of the 2 sides are Unequal Angle. Heavier Angle Iron is often used as a structural element in buildings and bridges, while lighter Angle Iron is used for a variety of supports such as an adjustable bed frame.

Structural channel, U channel, Tee (T-shaped cross-section), Steel Bar are also widly used Structural steel in the manufacture and fabrication of a broad range of engineered products, furniture making, machinery manufacturing, shipbuilding, railway spare parts, iron towers, and boilers, etc.

There are many factors considered when choosing a construction material. Cost is commonly the controlling element; however, other considerations such as weight, strength, constructability, availability, sustainability, and fire resistance will be taken into account before a final decision is made

Most construction projects need hundreds of different materials. Many commercial and industrial structures are mainly built using either structural steel or reinforced concrete. When building a structure, you must decide which, if not both, material is most suitable for the design. There are numerous points considered when choosing a construction material. Cost is commonly the controlling element; however, other considerations such as weight, strength, constructability, availability, sustainability, and fire resistance will be taken into account before a final decision is made.
