Slit coils in168mm and 188mm Slit in SS Grade 550 / Grade 80,

Z275 GSM in ASTM A653 for Light Gauge Frame Systems

• ASTM A653 SS Grade 80 / G550 / SGC570 Steel Coil

Structure-building steel that has been hot-dipped zinc coated and has a splattered surface is known as G550 galvanised steel. It has a 550 MPa guaranteed minimum yield strength. In roll-formed sections, it is frequently used for structural purposes. As specified 168mm and 188mm Slit coils in SS Grade 550 / Grade 80, Z275 GSM in ASTM A653, our firm, DBM, enforces strict requirements to guarantee that all of the galvanised steel coils we produce and provide are of industrial grade. These coils are subsequently utilised to construct light gauge steel structures (LGS).

The A653/A653M Standard Specification for Zinc-Coated (Galvanized) or Zinc-Iron Alloy Coated (Galvannealed) Steel Sheet. This specification applies to steel sheets produced by the hot-dip method and coated with zinc (galvanised) or zinc-iron alloy (galvannealed). The name of this organisation is shortened to ASTM or American Society for Testing and Materials Standards. A-653 is one of its branch standard numerals. ASTM A653 is the specification for hot-dip galvanised iron alloy or galvanised steel sheets.

G550 / SGC570 is a hot dipped galvanised structural grade steel developed specifically to maximise the efficiency of cold formed steel construction projects. It provides the highest yield strength to minimise the total steel requirement in each of your engineered structures. It has a guaranteed minimum yield of 550MPa to maximise yield and lower build costs. Most importantly G550 is supplied with full compliance certificates to assure specifiers the materials are compliant to International Standards

G550 is the ideal steel specification for all structural steel framing applications to provide benefits in transportables & modular projects, high volume social housing, bespoke architectural designs or even light commercial applications

• Advantages of Using Grade 550 Galvanized Steel Coils for Light Gauge Frame Systems

• High Strength to Weight Ratio

Grade 550 / SGC570 galvanized steel coils have a high strength to weight ratio, making them an ideal choice for use in frame. Their high yield strength of 550 MPa ensures that frame made from this steel can withstand heavy loads without bending or warping.

• Corrosion Resistance for Longevity

The zinc coating on grade 550 galvanized steel coils provides excellent corrosion resistance, ensuring that purlins made from this steel remain strong and long-lasting even in harsh environments. This makes them a cost-effective choice for construction projects of all kinds.

• Cost-Effective Solution

Using grade 50 galvanized steel coils for frames is a cost-effective solution for builders and contractors. These coils are readily available and easy to work with, making them a popular choice for a wide range of construction projects. Additionally, their high strength and corrosion resistance make them a reliable and long-lasting choice for purlins and other structural components.
