Cold from process

PEB Steel Alliance also uses the Cold Form Process at the optimum level. PEB’s modern state of the art machineries facilitates the application of the cold forming process to the highest degree. PEB Steel uses the most superior quality steel with galvanized steel with G-90 (275 gm/m2) zinc coating.

Cold-formed steel applications can be traced back as early as the 1850s in both the United States and Great Britain. In the late 1920s and early 1930s cold-formed steel entered thebuilding construction arena with products manufactured by a handful of fabricators. Approximately 40% of the total steel used in buildingconstruction is cold-formed steel.

Cold-formed steel possesses a significant market share because of its advantages over other construction materials and the industry-wide support provided by various organizations that promote cold-formed steel research and products, including codes and standards development that is spearheaded by the American Iron and Steel Institute (AISI).

ADVANTAGES OF COLDFORMED STEEL

Cold-formed steel products are shaped at ambient temperatures from steel sheet, strip plate or flat bars by roll-forming machines, press brakes or bending brake operations.They can be produced in large quantities and at high speed with consistent quality. A typical automated rolling machine can run at a speed range of 75-400 feet per minute, and the products can be as small as a three-quarter inch wide cold-rolled channel section to as big as a thirty-six inch wide roof deck section. In addition, cold-formed steel possesses many advantages over other construction materials:

1. Lightweight - Cold-formedsteel components weigh approximately 35% to 50% less than their wood counterparts, which means easy handling during construction and transportation.

2. High-strength and stiffness - As a result of the coldforming process, cold-formed steel possesses one of the highest strength-to-weightratios of any building material.This high strength and stiffness advantage means better design flexibility, wider spans and better material usage.

3. Fast and easy erection and installation - Building components made of coldformed steel can be fabricated with high accuracy in a plant and then assembled on job sites, which greatly increases erection efficiency and ensures construction quality.

4. Dimensionally stable material - Cold-formed steel does not expand or contract with moisture content. In addition, it does not split or warp as time goes by.Therefore, it is dimensionally stable. Cracked gypsum sheathed walls, nail head popping and other common problems with wood-framed structures can be virtually eliminated in buildings with cold-formed steel stud walls.

5. No formwork needed - The use of cold-formed steel decks eliminates the formwork for pouring concrete floor. In addition, composite action between the steel deck and concrete increases floor strength and stiffness.

6. Durable material - Coldformed steel is durable because it is termite-proof and rotproof. In addition, galvanized cold-formed steel products can provide long-term resistance to corrosion.

7. Economy in transportation and handling - Lightweight cold-formed members or panels are easy to handle and to transport. In addition, they can be nested and bundled, reducing the required shipping and storage space.

8. Non-combustible material - Steel is a non-combustible material and will not contribute fuel to the spread of a fire. Thiscan result in better fire resistance and lower insurance premiums.

9. Recyclable nature - Steel products used in construction are infinitely recyclable, with no degradation in structural properties. It can be recycled and reused. Steel framed housing dramatically reduces the amount of trees consumed for residential construction, thus conserving one of nature's most precious resources
