I purchased galvanized steel sheets from their company earlier this year. They provide raw material certificates with clearly stated chemical composition and mechanical properties (yield strength, tensile strength, etc.), fully compliant with national standards. The adhesion between their material substrate and zinc coating is excellent; as long as your mold and process parameters are appropriate, there have been almost no instances of large-area zinc coating peeling or noticeable micro-cracks during bending.

If you're still concerned, I strongly suggest they send a sample for testing first. That's what we did; we bent it a few times, tested the zinc coating, and once the results came back, we had a clear understanding of its quality.

You can send us your warehouse structural drawings. Our team of technical engineers will conduct a professional analysis, comprehensively considering structural safety, economy, and supply convenience, to recommend the most suitable steel type (H-beams/I-beams/square tubes), specific specifications, material standards, and optimized usage estimates. After specification confirmation, we will provide a formal solution including detailed technical parameters, accurate FOB/CFR quotes, production cycle, and a complete set of material certificates (MTC). You can contact us via WhatsApp/WeChat +86 18810048889 and send the information.

The thickness of color steel tile is generally measured in millimeters (mm). Common thickness specifications cover multiple ranges from thinner to thicker, mainly including 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.2mm, 1.5mm, etc.

Color steel tile comes in various thicknesses, depending on its intended use. Specifications are generally measured in millimeters (mm). Common thicknesses include: 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.2mm, and 1.5mm.

In practical applications, four main thicknesses are commonly used: 0.3mm, 0.4mm, 0.5mm, and 0.6mm.
1. 0.3mm thick color steel tiles are thinner and suitable for temporary structures and warehouses with lower load-bearing requirements. This thickness is lightweight, easy to install, and relatively inexpensive.
2. 0.4mm thick sheets are relatively stronger and suitable for small factories and garages with certain load-bearing requirements, combining strength and economy.
3. 0.5mm thick sheets are suitable for large buildings and industrial facilities, such as large factories and stadiums, offering good load-bearing capacity and resistance to wind and rain erosion.
4. 0.6mm thick sheets are a thicker specification, used in applications requiring high load-bearing capacity and durability, such as roofs of high-rise buildings and exterior walls of important industrial facilities.
