Roofing Sheets

• Pre-Painted Color Coated Steel Roofing Sheets:

  • These are steel sheets that have been pre-coated with a layer of paint and are often used for roofing applications. The paint provides protection against corrosion and adds aesthetic value, making them a popular choice for residential, commercial, and industrial buildings.

  • The color coating is typically made of polyester or other types of durable paints and can withstand various weather conditions, providing longevity and reducing maintenance.

• Color Coated Cladding/Barricading Sheets (PPGL/PPGI):

  • Cladding Sheets are used for exterior covering of buildings, providing both aesthetic appeal and protection from the elements.

  • PPGI (Pre-Painted Galvanized Iron) and PPGL (Pre-Painted Galvalume) are types of steel that have been pre-coated with both a protective zinc or aluminum coating and a layer of paint. PPGI sheets have a galvanized coating (zinc), while PPGL sheets have a Galvalume coating (a mix of zinc and aluminum). Both provide enhanced protection against corrosion and are suitable for use in roofing, cladding, and barricading.

  • These sheets are used for constructing walls, facades, and temporary barricades, often in construction sites or as architectural cladding.

• Bare Galvalume Roofing Sheets (Non-Color):

  • These sheets are made from steel coated with an aluminum-zinc alloy (Galvalume), offering excellent resistance to rust and corrosion. Unlike the color-coated variety, these sheets are “bare,” meaning they don’t have a paint or color finish.

  • Bare Galvalume roofing sheets are typically used for industrial or commercial applications where the appearance of the material is secondary to its durability and corrosion resistance. They are long-lasting and are highly resistant to the effects of extreme weather.

• Crimping Roofing Sheets (Front Bend):

  • Crimped roofing sheets have a wavy or corrugated design, which enhances the strength and durability of the sheet while also improving the water flow off the roof.

  • “Front Bend” refers to the type of crimping or bending done on the sheets. This process helps them interlock more securely, providing better stability and preventing leaks in roofing installations.

  • These sheets are commonly used in agricultural buildings, warehouses, and factories where a robust roofing material is necessary.

• Accessories: Ridges, Gutters, and “L” Flashings:

  • Ridges: These are installed at the apex of the roof to cover the ridge joints between roofing sheets. They provide a finished appearance and help prevent water ingress at the roof’s highest point.

  • Gutters: These are essential for directing rainwater away from the roof and the building’s foundation. Gutters are typically installed along the eaves of the roof.

  • “L” Flashings: These are metal strips shaped like the letter “L” and are used at joints, intersections, or edges to prevent water from seeping into the building. They provide waterproofing and are used in roofing and cladding systems.
