Advantage

  • Ability to span long lengths using high tensile steel
  • PosMAC® Steel used has 3-4 times more life than GI coated steel
  • Light Weight hence Low Handling and Transportation Cost
  • Tailor-made section lengths hence No Wastage
  • Cost effective as steel structures have the best stiffness/price ratio
  • Structures are well protected against adverse climate conditions.
  • No site drilling/cutting required
  • 25 years of maintenance-free life
  • Easy & Fast to Assemble

Surface Treatment

  • Multicolor offers PosMAC® which is ternary alloy coated steel (Zn- 3%Mg- 2.5%Al) with high corrosion resistance developed with POSCO's own technology that is 5 to 10 times stronger resistant than that of a normal hot-dip galvanized steel sheet [GI, GI(H)] with the same coating weight.
  • Multicolor offers Cee & Zed in Galvanised coated Steel in 175GSM / 275GSM / 550GSM Coating as per customer requirement for high corrosion environment.
  • Multi-Zed and Multi-Cee made of Hot Rolled Coils are degreased, phosphated and then primer finished with Zinc Chromate Red Oxide Paint- matching test requirement of IS : 4777 and IS : 2074. Special Treatment to combat severe atmosphere corrosion can be offered.

Systems of Connections

There are three systems of connections based on design of purlins and its connections.

About PosMAC®

PosMAC (POSCO Magnesium Aluminium alloy Coating product) is a ternary alloy coated steel (Zn- 3%Mg- 2.5%Al) with high corrosion resistance developed with POSCO's own technology.

Product characteristics
  • PosMAC is a corrosion resistant product that is 5 to 10 times stronger resistance than that of a normal hot-dip galvanized steel sheet [GI, GI(H)]with the same coating weight. PosMAC has an excellent cross-section corrosion resistance; normal thick plating products can be replaced with this product.
  • The same processing, assembly and painting process can be applied to PosMAC as one would apply to GI. 

  • High Tensile Steel
  • High tensile steel 550mpa is recommended for better strength and light weight.

  • Warranty
  • Manufacturer provides warranty of 15 years and 25 years for PosMAC® Steel (registered trademark of POSCO).

  • Corrosion resistance of PosMAC

    Why PosMAC® has excellent corrosion resistance?

  • The magnesium (Mg) in PosMAC's coating layer will accelerate the formation of a dense corrosion product called " Simonkolleite (Zn5(OH)8Cl2H2O) " which is extremely stable. When simonkolleite is formed on the surface of the coating layer in a film-like-form, it plays a role of a corrosion inhibitor for the base metal
  • In addition, the upper coating layer can be dissolved to cover the cross-section and accelerate the growth of a stable corrosion product. However red-rust can be found in the already exposed steel plate, but fortunately, the film of the corrosion products covers the cross-section and serves to prevent corrosion.
