Unequal Angle Steel
Unequal angle steel can be divided into two types: unequal thickness and unequal thickness.
GB/T2101-89 (General provisions for section steel acceptance, packaging, marking and quality certificates); GB9787-88/GB9788-88 (hot-rolled equilateral/unequilateral angle steel size, shape, weight and allowable deviation); JISG3192- 94 (shape, size, weight and tolerance of hot-rolled section steel); DIN17100-80 (quality standard for ordinary structural steel); ГОСТ535-88 (technical conditions for ordinary carbon section steel).
According to the above-mentioned standards, unequal-sided angles shall be delivered in bundles, and the number of bundles and the length of the same bundle shall comply with the regulations. The unequal angle steel is usually delivered naked, and it is necessary to pay attention to moisture-proof during transportation and storage.
Angle Steel-There are two kinds of equal angle steel and unequal angle steel. The specification of unequal angle steel is expressed by the dimensions of side length and side thickness. Refers to steel with an angular cross section and unequal lengths on both sides. It is a kind of angle steel. Its side length ranges from 25mm×16mm to 200mm×125mm. Rolled by a hot rolling mill. Unequal angle steel is widely used in various metal structures, bridges, machinery manufacturing and shipbuilding industries.
