Product Description

Product Description

Channel steel is a hot-rolled steel section with a grooved cross-section, manufactured strictly in accordance with the national standard GB/T 706-2016. The mainstream materials used are Q235B and Q355B carbon structural steel and low-alloy steel. It is integrally formed by hot rolling and can also be treated with hot-dip galvanizing, painting, or other anti-corrosion surface treatments according to application requirements.

The product boasts excellent mechanical properties and strong adaptability for welding, riveting, and processing. Product models cover the entire series from 5# to 40#, divided into two main categories: ordinary channel steel and light channel steel. Specifications are divided according to web height, flange width, and web thickness, with standard lengths ranging from 6 to 12 meters.

Custom processing services such as cutting, drilling, and bending are also supported. The profiles are neat, dimensionally accurate, and free from obvious defects such as twisting, deformation, and cracks. With its unique grooved cross-section structure, this profile possesses excellent bending, compressive, and torsional resistance, stable load-bearing capacity, high structural strength, and flexible installation methods. It can be combined with other steel sections through welding, bolting, and other methods, making construction convenient and efficient.

With its numerous advantages, channel steel is widely used in building construction projects such as steel frames for factory buildings, curtain wall supports, and platform columns. It is also commonly used in the machinery manufacturing field, such as machine frames, bases, vehicle chassis, and mining equipment parts. In addition, it is widely used in infrastructure and logistics scenarios such as bridge support, tunnel engineering, warehouse racking, port equipment bases, and power transmission towers. The materials are all sourced from well-known domestic steel mills, ensuring reliable quality and meeting the usage standards of various engineering and industrial projects.

Production workshop

This channel steel production workshop utilizes an integrated hot-rolling production line with a high degree of automation and smooth production process. Raw materials undergo heating, continuous rolling, straightening, and length cutting to achieve the desired shape. Multiple quality inspection stages are implemented throughout the process to strictly control product dimensions, appearance, and mechanical properties. The workshop is rationally zoned, and the equipment operates stably. It can mass-produce all specifications of national standard channel steel and also undertake various deep-processing customized orders. With ample production capacity and strict quality control, it ensures consistent delivery standards and reliable product quality.

Packaging & Shipping

The channel steel is packaged using standard professional steel packaging methods, typically in full bundles reinforced with multiple layers of high-strength galvanized steel straps. The straps are evenly spaced, ensuring a tight and secure bundle to prevent shifting, bumping, or scattering during transport. Corner protectors and sleeves can be added to both ends to prevent wear and deformation. The surface is covered with waterproof and rainproof woven fabric or plastic film as needed to isolate rainwater, dust, and moisture, effectively preventing oxidation and rust. Each bundle is clearly labeled with product specifications, material, theoretical weight, batch number, production date, and inspection information for easy inventory, identification, and warehouse management.

During transportation, freight vehicles and trailers are flexibly selected based on the weight, volume, and delivery distance of the goods. During loading, the materials are arranged logically and stacked in layers, using wooden blocks and spacers for isolation and fixation to prevent surface scratches and deformation caused by mutual compression and friction. Long-distance transport is protected against rain and collisions throughout the journey. Short-distance delivery strictly adheres to loading and unloading standards, using professional lifting equipment to prevent rough handling. The entire vehicle is securely reinforced, ensuring stability and safety during transport. It is compatible with various modes of transportation, including land transport and multimodal transport. We oversee every stage of loading, transshipment, and unloading to guarantee that the channel steel arrives at its destination in perfect condition. We can also customize loading and unloading solutions and provide door-to-door delivery according to customer requirements, meeting the supply needs of different regions and projects.
