It resists ammonia/water vapor erosion, 1500h salt spray test, no coating peeling after 4 years; 90% recovery rate for disassembly and reuse (50% lower secondary cost). 3,000㎡ roof completed in 7 days for a high-speed rail temporary project.

Our Industrial Advantages

Shunchen Industry has nearly 20 years of technical accumulation in color steel roofing sheet manufacturing, focusing on coating technology and profile design. It integrates 8 core processes (cold rolling, roll coating, etc.) with original double-sided coating three-pass curing technology to form a standardized production system. Products reach 0-grade coating adhesion, with weather resistance far exceeding GB/T12754-2019. Customizable profile and coating schemes for different scenarios, leading in both quality and cost performance.

FAQs

Q1: What factors should be considered when selecting the coating type of color steel roofing sheets?

A: For indoor/dry inland areas, PE coating is cost-effective; for coastal high-salt-spray or outdoor long-term use scenarios, PVDF coating is recommended; for agricultural greenhouses with harsh environments, HDP coating is the optimal choice.

Q2: Can the color steel roofing sheet be customized with special colors and logos?

A: Yes, we support customized roll-coating of special colors according to RAL/Pantone color cards, and can also print project logos or anti-counterfeiting marks on the sheet surface as required.

Q3: What is the delivery time for customized color steel roofing sheet orders?

A: For standard specification orders, the delivery time is 3-5 working days; for small-batch customized profiles/coatings, it is 7-10 working days; for large-scale project orders, we will confirm the delivery schedule according to the construction node and production capacity.

Q4: Do you provide on-site installation guidance and after-sales maintenance services?

A: Yes, we have a professional technical service team to provide on-site installation guidance and construction technology training. We also provide a long-term after-sales maintenance service, and respond to quality problems within 24 hours for on-site handling.

Q5: What is the MOQ for color steel roofing sheet orders, and do you support sample provision?

A: There is no strict MOQ; we support small-batch trial orders for project testing. Free samples (within 1 square meter) can be provided, and the customer only needs to bear the freight cost.
