Heat Insulated Color Steel Sheet - Factory Price Supplier
Heat insulated color steel sheet has become an indispensable material in modern construction, delivering an exceptional combination of thermal efficiency, structural durability, and aesthetic appeal. As global demand for energy-efficient building envelopes continues to rise, this composite panel solution finds extensive application in industrial warehouses, cold storage facilities, commercial roofing systems, agricultural structures, and prefabricated buildings. Engineered to minimize heat transfer while maintaining the mechanical integrity of galvanized or Galvalume steel substrates, these panels significantly reduce HVAC energy consumption — studies indicate thermal resistance values (R-value) ranging from R-10 to R-38 depending on insulation core thickness. The color-coated surface, available in a spectrum of RAL and custom shades, provides outstanding anti-corrosion properties with a service life exceeding 25 years under standard atmospheric conditions. Whether you are sourcing materials for a large-scale commercial project or a specialized industrial facility, our mill-direct supply chain ensures consistent quality at highly competitive rates.
What is Heat Insulated Color Steel Sheet?
Heat insulated color steel sheet is a composite building panel consisting of a color-coated steel facing layer — typically pre-painted galvanized steel (PPGI) or Galvalume steel — bonded to a rigid thermal insulation core such as expanded polystyrene (EPS), polyurethane (PU), or rock wool. This sandwich construction delivers simultaneous load-bearing capacity, weatherproofing, and thermal regulation, making it a premium grade solution for energy-conscious construction applications worldwide.
Heat Insulated Color Steel Sheet Manufacturing Process
Production begins with cold-rolled steel coils that undergo hot-dip galvanizing or Galvalume coating to achieve a zinc layer of 60–275 g/m². The substrate is then chemically pretreated, primer-coated, and finished with a polyester, PVDF, or SMP topcoat at thicknesses of 15–25 μm. The insulation core — EPS at densities of 14–18 kg/m³, PU foam at 40–45 kg/m³, or rock wool at 100–120 kg/m³ — is continuously laminated or injected between the steel facings under controlled pressure and temperature, forming a monolithic panel with superior bond strength exceeding 0.1 MPa.
Heat Insulated Color Steel Sheet Technical Specifications
Standard panel widths range from 950 mm to 1,200 mm with customizable lengths up to 12,000 mm. Steel substrate thickness spans 0.3 mm to 0.8 mm per GB/T 12754 and ASTM A755 standards. Core thickness options of 50 mm, 75 mm, 100 mm, 150 mm, and 200 mm yield thermal conductivity values (λ) as low as 0.022 W/(m·K) for PU cores. Fire resistance ratings achieve Class A1 with rock wool cores per EN 13501-1. Bending strength of the panel system reaches a minimum of 120 MPa, ensuring structural reliability under wind and snow loads.
