fAQ
Q: What African projects are your steel angles suitable for?
A:Our equal and unequal steel angles are widely used in African infrastructure projects, including factory steel structures, power transmission towers, bridge supports, road guardrails, warehouse construction, mining equipment frames, agricultural greenhouses, and civil building structures. They are adaptable to engineering needs in West Africa, East Africa, Southern Africa, and other regions.
Q:What materials and specifications are available for the steel angles?
A:Common materials: Q235, Q355, S355JR, ASTM A36, etc.;
Specifications: 20×20mm to 200×200mm (size), 3–24mm (thickness); standard lengths: 6m, 9m, 12m. Custom lengths are available upon request for specific projects.
Specifications: 20×20mm to 200×200mm (size), 3–24mm (thickness); standard lengths: 6m, 9m, 12m. Custom lengths are available upon request for specific projects.
Q: Do you provide galvanized steel angles? Are they suitable for coastal/desert areas in Africa?
A:Yes, we offer both hot-rolled black steel angles and hot-dip galvanized steel angles.
Galvanized steel angles feature superior corrosion and rust resistance, making them ideal for high-humidity coastal areas and sand erosion-prone desert regions in Africa. They can significantly extend service life and reduce long-term maintenance costs.
Q: Do the products meet customs clearance requirements? Can you provide relevant certificates?
A:Yes.We can supply necessary customs clearance documents including ISO inspection reports, material certificates, packing lists, commercial invoices, and certificates of origin. For certain countries, we can assist in obtaining COC and other compliance documents to minimize customs clearance risks for customers.
Q:What is the minimum order quantity (MOQ)? Do you support small trial orders?
A:Trial orders are supported.The MOQ is generally one container or based on tonnage, subject to port and packaging requirements. Small trial orders and sample orders are available to facilitate product inspection and preliminary project procurement.
