Metal Roofing

Metal roofing is durable, lightweight, efficient, fire resistant and environmentally friendly. Although metal roofing is more expensive than its more common cousin-asphalt-it far outlasts it. It has been known to last as long as 50 years.

The energy efficiency of metal roofs is impressive. As much as 70% of the sun can be reflected, thus drastically reducing cooling costs. It will also help maintain the temperature inside at a comfortable level and keep the cost of heating down.

Metal roofing is an environmentally friendly option for today’s builder and homeowner. The steel used for metal roofing products is made of as much as 50% recycled materials. It is also completely recyclable itself. Some contractors will install metal roofing materials over existing asphalt shingles, thus reducing waste in a landfill.

Metal roofing material can be made of copper, galvanized steel, coated steel, stainless steel or aluminum. There are several options for panel construction – standing seam, decorative stampings and many others. Color choices are endless and can please even the pickiest client.

Most homes in hurricane-prone areas benefit greatly from metal roofing choices. Experience proves that high winds often leave these roofs intact. They are also resistant to heavy rain, damaging hail and snow and ice which can result in lower insurance rates for homeowners. Metal roofing may well be the choice of future roofs!

China steel suppliers more and more these years, customers more pay attention to quality. Choose a reliable supplier is particularly important. Customers could check suppliers of production scale, established time, shipment situation, shipping photos and Mill Test Certificate and so on. It’s very important to discuss about delivery time, a great number of suppliers guarantee 15 days shipment, but general they can’t deliver products on time. Because produce 50MT to 500MT corrugated galvanized sheet need 20~30 days usually.

Galvanized steel price decides the price of corrugated galvanized roofing sheet. Because galvanized steel is base plate for corrugated galvanized sheet.

Galvanized angle iron supplier is not necessarily the common angle iron manufacturer. Because galvanized angle iron is by the angle iron then making galvanized, sometimes, the angle iron factory can’t make galvanized process, so we need to find the professional galvanized mill to galvanize for our angle iron after which we can get the galvanized angle iron. So the galvanized angle steel price is always higher than the angle iron price about 800-1200 rmb / ton more or less.

Galvanized Angle Iron is the angle after derusting into around 500 ℃ melting liquid zinc through which the zinc layer is adhered on the surface of the angle steel, thereby reach the purpose of anticorrosive, it’s suitable for all kinds of acid, alkali fog corrosive environments.

Galvanized Angle Iron has many advantages just like the following list

No. 1 Low processing cost: the cost of the hot dip galvanized anti-rust cost is lower than other paint coating.

No. 2 Durable: hot dip galvanized Angle steel has surface luster, uniform zinc layer, no plating leakage, no DiLiu, strong adhesion, corrosion resistance strong features. In the suburbs environment, standard hot-dip galvanized anti-rust thickness can be 50 years without repair, and in urban areas or coastal area, the standard of hot-dip galvanized anti-rust layer can keep 20 years without repair.

No. 3 Good reliability: between the galvanized layer and steel there is the metallurgical combination. It’s a part of the steel surface which can make the durability of coating more reliable.

No. 4 Coating of high tenacity: galvanized layer to form a kind of special metallurgical structure, this structure can bear the mechanical damage during transport and use.

No. 5 Comprehensive protection: each section of the plated parts can zinc plating, even in the cavity, sharp corners and hiding places can be fully protected.

No. 6 Save time and effort: galvanized process faster than other coating construction method, and can avoid the time needed for brushwork at site after installation.

Galvanized angle iron has very widely use with tower, communication tower, railway and highway protection, lamp posts, Marine structures, construction steel structure component, ancillary facilities of substation, light industry, etc.

Angle iron is becoming more and more important in building structures and engineering structures to fulfill our daily life. There are so many angle iron suppliers in China and the angle iron prices are competitive. Among them, Steel from China guarantees great quality and reasonable prices.

Angle iron is mainly used to make the frame structure, such as high-voltage transmission tower, steel bridge frame on both sides of the tower, crane on the construction site of the column and arm, workshops columns and beams, some small places like the roadside flowerpot shape shelf, hanging shelf solar air conditioning in windows. Angle of the surface quality requirements in the standard, general requirements may not exist in the use of harmful defects such as delamination, scarring, and cracks. Angle iron geometry of the allowable range in the standard deviation is also provided, generally comprises a curved edge, width edge, other items of the theoretical weight and the predetermined angle of twist can not be significant.

The manufacturing process of angle iron is relatively simple, and according to the production technique angle iron can be divided into two types which are hot-rolled and cold-formed. Hot rolled steel angle is large, while cold-formed is relatively smaller. Standard process is billet through a dedicated many channels repeatedly rolling steel mills gradually rolled into v shape. There is a transition in the inner corner of the arc with reliable mechanical properties. Rather small workshop production is directly rolled sheet or strip with a curve into the inside corner no transition arc, and because the larger the bending stress in a corner, and poor mechanical properties, the most important point is that the material is not guaranteed, this generally can not buy back angle bend, nor welding, drilling up to take the length. Angle steel billets for the production of raw material for carbon square steel billets, hot rolled angles finished forming, hot-rolled or normalizing the status of delivery.

Angle Iron and price

As we all know, China steel has advantage on price and with excellent quality. Steelfromchina.com is the most representative China steel which gathering first class Chinese factories especially for structural steel. Among them, angle iron is one of the most popular and useful structural steel.

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. Usually the two sides of the angle are of equal length. Heavier angle iron is often a structural element in buildings, bridges, and so on, while a lighter version is used for a variety of supports. An adjustable bed frame, for example, is made of this material.

Iron and steel are the most common materials used to make this mate, especially when it will be used in a structural framework. In these cases, the rod is often called angle steel or steel angle iron. Aluminum is used when weight or rust are important considerations. Brass angle iron is sometimes used in projects, especially when the rod will be visible in the finished work and aesthetic appeal is important. Sometimes angle iron is sold with a powder finish that resembles paint.

Angle iron is available in several standard sizes, usually expressed by naming the length of one side. That with longer sides is typically made of thicker metal and has a thicker “root,” the area where the bend is located. Larger versions can support heavier loads

Slotted or pierced angle iron has holes at standard intervals along both sides. Usually the holes are one inch (2.54 cm) apart as measured from the center of each hole. The holes are oval rather than round to allow for different stress in the finished product. Slotted angle iron is often used for uprights in commercial shelving, since sections are easy to assemble with nuts and bolts. Precut lengths with formed metal shelves are often packed and sold as garage shelving.

Angle brackets are sometimes called angle irons. These are also L-shaped pieces of metal, but the fold runs across the width of the flat metal rod instead of along its length. Angle brackets are often bolted to the wall and used to support shelves.
