En10034 56565 Structural Dedicated Angle Steel & Angle Iron, High Tensile Strength, for Building Load Frame, Custom Cutting Processing

Product Description

Product Description

 

Angle steel, also commonly known as angle iron, is a long strip of steel with a standard L-shaped cross-section. Its perpendicular sides make it an indispensable basic steel material in the construction and industrial fields. The products are manufactured strictly according to national standards and are mainly divided into two categories: equal-sided angle steel and unequal-sided angle steel. A complete range of specifications are available, with various widths and thicknesses covering common dimensions to meet the needs of different working conditions.

The mainstream material for this product is Q235B carbon structural steel, but versions in Q355B low-alloy high-strength steel and stainless steel are also available. The material has stable performance, possessing excellent strength, toughness, and compressive and shear resistance. It has uniform stress distribution and is not easily deformed or bent over long-term use. The steel surface is neatly finished, using mature hot-rolling technology, resulting in a uniform and smooth paint and coating. It exhibits good rust and oxidation resistance and a long service life.

Angle steel has excellent processing performance, supporting secondary processing such as cutting, welding, drilling, and bending. Assembly and connection are simple and convenient, significantly improving construction and installation efficiency. Compared to other profiles, it is lighter, uses less material, and offers outstanding overall cost-effectiveness. With its reliable overall performance, the product has a wide range of applications, suitable for building steel structure frames, curtain wall joists, scaffolding, stair components, and other construction projects, as well as for power transmission towers, bridge reinforcement, machinery and equipment supports, warehouse racking, vehicle parts, and other fields.

We can customize special specifications and processing services according to customer needs. All products undergo rigorous quality inspection before leaving the factory, ensuring quality and making them the preferred profile for various engineering projects and industrial manufacturing.

Detailed Photos

Equal-sided angle steel has two sides of equal width, while unequal-sided angle steel has two sides of different widths. Standard specifications range from 20mm to 200mm, with various thickness options. Dimensional tolerances strictly adhere to national standards, resulting in regular cross-sections, high right-angle accuracy, and no obvious deflection or twisting.

The mainstream materials used are Q235B and Q355B carbon and low-alloy steel, with 201 and 304 stainless steel also available upon request. The raw materials are of high purity, with uniform metallographic structure, stable tensile, compressive, and bending strength, strong load-bearing capacity, and resistance to brittleness at low temperatures.

Production utilizes a hot-rolling process, resulting in a uniform surface color and a natural, smooth hot-rolled texture, free from defects such as cracks, scars, delamination, bubbles, and slag inclusions. The end faces are cut smoothly with minimal burrs and clear, smooth edges; the steel is dense internally, with no looseness or voids in the cross-section. Standard products are made of black raw material, but surface treatments such as galvanizing, painting, and rust removal are also available. The galvanized layer has strong adhesion and uniform thickness, which greatly improves the ability to prevent rust and corrosion, making it suitable for complex working conditions such as outdoor, humid, acid and alkali environments.

Production workshop

The angle steel production workshop has a well-organized layout and clear workflow, implementing standardized assembly line operations. Equipped with advanced hot rolling mills, straightening equipment, cut-to-length machines, and quality inspection instruments, the workshop ensures seamless integration of each process, from raw material feeding, heating and rolling, forming and cooling, to straightening, cut-to-length cutting, and finished product sorting.

Raw materials are clearly zoned, and steel billets are categorized and clearly labeled. After high-temperature heating, the steel is rolled into standard L-shaped sections. After forming, multiple straightening processes correct the shape, ensuring precise right angles and a flat surface. Cutting precision is controllable, resulting in smooth, burr-free ends.

Strict quality control is maintained on-site. Quality inspectors randomly inspect each batch for dimensions, appearance, and mechanical properties, rejecting products with cracks, deformation, or thickness deviations. Finished products are bundled and neatly stacked according to specifications and materials. The workshop has complete safety facilities, operates in a standardized and orderly manner, and implements comprehensive quality control, enabling stable production of national standard equal-leg angle steel, unequal-leg angle steel, and galvanized angle steel to meet various engineering and processing needs.

Packaging & Shipping

Packaging:
Angle steel is primarily packaged using steel strapping. Bundles of the same specifications and material are grouped together, with uniform weight and tight, evenly spaced straps to prevent loosening and shifting during handling and stacking. Corner guards are added to protect the edges and corners from impacts and deformation.

For black angle steel without anti-corrosion treatment, a waterproof woven fabric/plastic film can be used to isolate moisture and dust. Hot-dip galvanized angle steel is bundled separately to prevent scratches and wear on the coating. Each bundle is labeled with clear specifications, material, weight, furnace batch number, and applicable standards, providing clear categorization for easy inventory and storage. Custom-made wooden frames can be used for reinforcement in special needs.

Transportation:
Short-distance transport is done by truck, while long-distance transport uses containers or open wagons. During loading, the steel is stacked according to specifications, with cushioning materials between layers to ensure stable stacking and balanced stress, preventing rolling and collisions during transport.

Rain protection is provided throughout the journey. In rainy weather, tarpaulins are used to cover the steel to prevent moisture and rust. Forklifts and lifting equipment must be used for loading and unloading in a standardized manner; throwing or dropping is strictly prohibited. Goods can be delivered directly to the construction site and warehouse; the logistics routes are well-established, ensuring timely and intact delivery of goods.
