China Cheap price Channel Steel - Hot Rolled Unequal Angle Steel – JINBAICHENG

product quality

The surface quality of unequal angle steel is stipulated in the standard, and it is generally required that there should be no harmful defects in use, such as delamination, scarring, and cracks.

The allowable range of geometric shape deviation of unequal angle steel is also specified in the standard, which generally includes items such as curvature, side width, side thickness, top angle, theoretical weight, etc., and stipulates that unequal angle steel must not have significant torsion

Specification

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 generally delivered naked, and it is necessary to pay attention to moisture-proof during transportation and storage.

It is widely used in various municipal public, civil construction and military industrial structures and engineering structures, such as industrial building beams, bridges, power transmission towers, lifting and transporting machinery, ships, industrial furnaces, reaction towers, container racks, and Warehouses, etc., because their consumption is less than single-sided angle steel, the relative price is slightly higher.

product advantages

1. Low processing cost: the cost of hot-dip galvanizing and rust prevention is lower than that of other paint coatings;

2. Durable and durable: Hot-dip galvanized angle steel has the characteristics of surface gloss, uniform zinc layer, no leakage plating, no dripping, strong adhesion, and strong corrosion resistance. In the suburban environment, the standard hot-dip galvanizing anti-rust thickness can be maintained Over 50 years without repairing; in urban areas or offshore areas, the standard hot-dip galvanized anti-corrosion layer can be maintained for 20 years without repairing;

3. Good reliability: The galvanized layer and the steel are metallurgically bonded and become a part of the steel surface, so the durability of the coating is more reliable;

4. The coating has strong toughness: the zinc coating forms a special metallurgical structure, which can withstand mechanical damage during transportation and use;

5. Comprehensive protection: every part of the plated parts can be plated with zinc, even in recesses, sharp corners and hidden places can be fully protected;

6. Time-saving and labor-saving: the galvanizing process is faster than other coating construction methods, and it can avoid the time required for painting on the construction site after installation.

Product Usage

Galvanized angle steel is widely used in power towers, communication towers, curtain wall materials, shelf construction, railways, highway protection, street light poles, marine components, building steel structural components, substation ancillary facilities, light industry, etc.
