Rail steel is usually used for railway fixed on the sleeper, sleeper for ballast. It is fastened by rail support, fastener, rail press, track splint, elastic bar, railway spike and other railway accessories. The bottom of the track is the track bed, which provides elasticity and drainage function for the track. Rails can also be laid on bases made of concrete, or even embedded in concrete. In order to withstand the pressure, impact load and friction of train operation, it requires sufficient strength and certain toughness. Quality requirements are strict, in addition to the guarantee of its chemical composition, but also require the inspection of mechanical properties, drop weight test and acid leaching of low-power tissue.

Compared with other metal wires, aluminum wires have distinct advantages: they are lightweight (with a density of 2.7 grams per cubic centimeter, facilitating transportation and installation), cost-effective (lower than copper wires), have excellent corrosion resistance (the natural oxide layer can prevent oxidation), and have good ductility (can be bent and shaped without being damaged, thereby reducing processing and installation costs).

Glass fiber reinforced plastic (FRP) grating, also known as FRP grating, is a plate-shaped material with many spaces that is made of glass fiber as a reinforcing material and unsaturated polyester resin as a matrix. It is compounded through special processing. Fiberglass grating can be used as structural materials for floors, trench covers, platforms, ship decks, stairs, planks, etc. in corrosive environments. It has the characteristics of corrosion resistance and flame retardancy, non-magnetic insulation, bright colors, and a variety of styles to choose from.

Steel grating is also called steel grating. The grating is a steel product made of flat steel arranged crosswise with horizontal bars at certain intervals and welded into a square grid in the middle. It is mainly used to make ditch covers. , steel structure platform plates, steel ladder treads, etc. The cross bars are generally made of twisted square steel.

Spiral steel pipe is a spiral seam steel pipe made of strip coil plate, extruded at constant temperature and welded by automatic double-wire double-sided submerged arc welding process. The spiral steel pipe will send the strip into the welding pipe set. After being rolled by a multi-channel roll, the strip gradually rolls up to form a circular tube blank with an open gap. The pressure of the extrusion roll is adjusted so that the weld gap is controlled within 1~3mm and the two ends of the welding joint are flush.
