SAE/AISI/ASTM 1045 channel steel is a groove-shaped cross-section of the steel strip. Sectional shape of the trough-shaped steel. Channel steel is mainly used for building structure, vehicle manufacturing and other industrial structures and fixed disk cabinets, etc., and I-beam channel often used in conjunction.

SAE/AISI/ASTM 1045 angle steel may require different structural composed of various members of the force, but also for connections between components. Widely used in various building structures and engineering structures such as beams, bridges, transmission towers, lifting and transport machinery, ships, industrial furnace, reaction tower, container frame and warehouse.

SAE/AISI/ASTM 1045 H-beam steel building is a new economy. H-beam cross-sectional shape economically reasonable, good mechanical properties, rolling more uniform cross-section extending points, internal stress, compared with the conventional beam, having a section modulus, light weight, the advantage of saving the metal is steel.

H-beam steel an economic cross-section steel, widely used in industrial, construction, bridges, oil drilling platforms:

Steel industrial structures bearing bracket
Steel piles and supporting structure underground engineering
Petrochemical industrial equipment construction and electricity
Large-span steel bridge member
Shipbuilding, machinery manufacturing framework
Trains, cars, tractor beam bracket
Port belt, high-speed shutter bracket

SAE / AISI / ASTM 1045 I-beam cross-section is a more excellent mechanical properties of economic section steel, compared with the general steel, low-cost, high-precision, low residual stress, without expensive welding materials and weld inspection, saving the cost of steel production 30 %about. Compared with the concrete structure, I-beam structural can be increased by 6% use of space, and to reduce the structural weight by 20% to 30% reduction in the structural design internal forces. T beam processed into steel, castellated beams may be combined to form various cross-sectional forms, engineering design and production to meet the great demand.
