Recommended Outdoor Building Color-Coated Steel Sheets Coating

Polyvinylidene fluoride (PVDF) coated steel sheets are the top choice for high-end outdoor projects. PVDF coatings boast excellent UV resistance, acid and alkali resistance, and weather resistance, with an outdoor lifespan of 15-20 years, far exceeding PE, SMP, and HDP coatings, making them a popular material for building envelope systems and roofing. Why is PVDF […]

Color-coated Steel Sheet Uses

Color-coated steel sheet encompasses both painted steel sheets and laminated steel sheets. Due to its outstanding weather resistance (UV resistance), corrosion resistance, color durability, mechanical strength, formability, fingerprint resistance, scratch resistance, and high decorative appeal, it is widely used in construction, home appliances, engineering projects, and other fields.

Color-Coated Sheet Thickness Selection Guide

Color-coated steel sheets (PPGI sheets, PPGL sheets) are popular building materials that play a vital role in architectural walls, roofs, ceilings, partitions, and floor decking structures through various forms such as flat sheets, corrugated sheets, and profiled sheets. The thickness of color-coated steel sheets determines their durability, corrosion resistance, tensile/compressive strength, snow load capacity, and

VCM vs. PCM

VCM stands for Vinyl Clad Metal or Vinyl Laminated Metal, referring to vinyl-coated metal panels. PCM stands for Pre-Coated Metal, referring to pre-coated steel sheets. VCM and PCM are two common metal surface treatment methods. PCM has lower processing costs and is widely applied. VCM is a more advanced surface treatment technology developed from PCM,

Surface Treatment of Galvanized Steel: Phosphating vs. Passivation

The core objective of surface treatment for galvanized steel is to “play to its strengths while mitigating its weaknesses”—preserving its excellent rust prevention (red rust resistance) capabilities while overcoming drawbacks such as susceptibility to white rust and poor coating adhesion. Currently, Wanzhi Group’s primary surface treatments for galvanized steel include passivation, phosphating, coating, sealing, and

Aluzinc Steel for Photovoltaic Mounting Structures

Photovoltaic mounting systems require long-term outdoor use and demand high corrosion resistance. Currently, commonly used corrosion-resistant metal materials include galvanized steel, galvanized aluminum-zinc steel, zinc-aluminum-magnesium alloys, aluminum alloys, and stainless steel. Among these, aluminum-zinc coated steel has gained prominence due to its exceptional cost-effectiveness. It is increasingly playing a vital role in components such as
