Raw Material Preparation-The Manufacturing of lattice tower
The primary material for angle steel towers（lattice tower）is hot-rolled angle steel, supplemented by steel tubes and plates. The quality of these materials directly determines the bearing capacity and service life of the tower. We strictly procure in accordance with national standards (GB/T 706, GB/T 1591), European standards (EN 10025), or American standards (ASTM A36/A572). Steel grades range from Q235 and Q355 to Q420, and even high-strength weathering steel.
Product Info
All steel comes from ISO-certified major mills and is accompanied by complete mill test certificates. Upon arrival, materials undergo physio-chemical inspection, including spectral analysis for chemical composition, tensile testing for mechanical properties, and dimensional checks, to guarantee that yield strength, tensile strength, and elongation fully comply with design and standard requirements. For steel plates and tubes requiring welding, we pay special attention to carbon equivalent to ensure weldability. Qingdao Best Tower has established a reliable supply chain system and sufficient standing inventory, enabling rapid response to projects with different international standards and guaranteeing the quality of every component from the source.
