Application

Designed for Trapezoidal Roofing Profile Manufacturing

Roll Forming Compatibility

Optimized for trapezoidal & corrugated tile roll‑forming machines. Balanced yield strength and elongation performance, no paint cracking or flaking during profiling.

Structural Durability

Compared with 1xxx series aluminum, 3004 & 3105 deliver higher tensile strength, ideal for long‑span trapezoidal roof panels and wall cladding.

Environmental Resistance

Well‑suited for Mediterranean and Middle‑East climate conditions. Excellent UV‑resistance and salt‑spray corrosion resistance for coastal environments.

Paint & Substrate Material Performance

Paint System & Substrate Performance

Substrate Chemical Performance: 3004 VS 3105

3004: Manganese‑magnesium alloy grade, higher mechanical strength. Preferred for trapezoidal roofing with high wind‑load requirements.

3105: Good bending & deep drawing capability, cost‑effective option for general roofing projects.

FAQs

Q1: Why choose 3004/3105 alloy instead of 1050/1100 for trapezoidal roofing sheets?

A: 3004 and 3105 alloys contain manganese and magnesium elements. They provide higher tensile strength and structural rigidity, effectively preventing trapezoidal roof panels from deformation under strong wind loads.

Q2: What coating grade do you recommend for tropical and Mediterranean coastal climates?

A: PVDF coating is highly recommended for high‑UV and salt‑spray coastal regions, offering more than 20 years outdoor weathering service life. HDP or PE coating is a cost‑efficient choice for standard industrial roofing projects.

Q3: What is the production lead‑time for one full 20ft container order?

A: Standard production lead‑time: 30 working days upon receipt of deposit and confirmed order details.
