S350GD High Strength PPGI Steel Coil Industrial Warehouse Roofing Wall Panel 0.5-1.0mm Z180

S350GD High Strength PPGI Steel Coil is a structural pre-painted galvanized steel coil developed for industrial warehouse roofing and wall panels that must carry load and span long distances. The S350GD substrate is a high strength structural steel with a minimum yield strength of 350 MPa, significantly higher than ordinary DX51D commercial grade, so thinner gauges can be used without losing load bearing capacity. The galvanized surface and durable polyester topcoat add corrosion protection and a clean, professional finish for industrial buildings.

Higher strength means the material can span further between purlins and resist wind and snow loads more effectively, reducing the number of supporting members and the total weight of the building envelope. The coil roll forms cleanly into trapezoidal sheeting and standing seam profiles for warehouse roofs and walls, factory buildings and logistics centres. Each coil is produced to international colour coating standards and supplied with a mill test certificate for full traceability.

• High Strength S350GD Substrate: A minimum yield strength of 350 MPa allows thinner gauges and longer spans without reducing load bearing capacity.
• Industrial Warehouse Roofing: Designed for warehouse roofing and wall panels, factory buildings and logistics centres that require structural strength.
• Load Bearing and Durable: Higher strength resists wind and snow loads better and lets the envelope span further between purlins, cutting support steel and weight.
• Corrosion Protection: A Z180 hot-dip zinc coating plus primer and topcoat protect the structural steel in industrial and outdoor environments.
• Clean Roll Forming: The coil roll forms cleanly into trapezoidal and standing seam profiles for roofing and cladding without cracking the paint film.
• Certified and Traceable: Produced under ISO 9001 management with SGS inspection and a mill test certificate covering yield strength, coating weight and thickness.

S350GD high strength PPGI steel coil is used for industrial warehouse roofing, factory wall cladding, logistics centre and distribution warehouse envelopes, steel structure buildings, workshops and hangars. It is also suited to large span roofing where fewer supports are preferred, to agricultural and cold storage buildings, and to any project that needs a strong, durable and attractive metal envelope. The combination of high strength, corrosion protection and clean finish makes it an efficient structural roofing and cladding material for modern industrial construction.

Q: What does S350GD mean?
A: S350GD is a structural steel grade with a minimum yield strength of 350 MPa, used when higher load bearing capacity is needed than ordinary commercial grades provide.

Q: Where is high strength PPGI used?
A: It is used for industrial warehouse roofing and wall panels, logistics centres, factory buildings and large span roofs that must carry wind and snow loads.

Q: What is the advantage of S350GD over DX51D?
A: S350GD has a much higher yield strength, so thinner material can span further between supports, reducing steel weight and building cost.

Q: Is this coil suitable for roll forming?
A: Yes. The ductile coating and structural substrate roll form cleanly into trapezoidal and standing seam profiles without cracking.

Each coil is wrapped with PE film and waterproof paper, secured with steel strapping and loaded onto fumigated wooden pallets for ocean transport. Every coil is labelled with grade, zinc coating weight, colour, thickness, coil number and weight for full traceability. We supply mill test certificates, SGS inspection reports and pre-shipment photographs on request, and our ISO 9001 certified process ensures consistent quality. Sample coils and colour chips are available for approval before mass production.
