29U Steel Arch

U-steel support is a kind of passive support of coal mine support, the tensile strength and the compressive strength is higher, it also has good toughness properties Material: 20Mnk Size: 29U Application: U-channel steel support is mainly used for the secondary support of mine tunnel and the mine tunnel of the mountain tunnel. Application: U-channel steel support is mainly used for the secondary support of mine tunnel and the mine tunnel of the mountain tunnel.

Application: U36 steel support is mainly used for mine tunnel, mine tunnel secondary support, as well as support through the mountain tunnel support purposes. U-shaped steel bracket Features: withstand pressure, support long time, easy to install and easy to deformation characteristics. 36U steel frame consists of a roof beams, two legs, four card cable, two bottom feet composition. Mainly used in mine tunnel, mine tunnel secondary support, as well as support through the mountain tunnel support and so on. Model: 36U Material: 20MnK Specification: single beam, double beam, treble beam, grade beam

Application: U-channel steel support is mainly used for the secondary support of mine tunnel and the mine tunnel of the mountain tunnel. Model: 40u Material: 20MnK Specification: single beam, double beam, treble beam, grade beam Characteristic: High initial support, strong support strength, easy installation and not easy deformation; high cross section utilization and small maintenance; the recycling rate is high, the use of timber is reduced and the environmental benefit is obvious.

U Shaped Steel Arch Clamp U Shape Steel Arches In Tunnel,Rail Clamp PRODUCT PARAMETERS U-shaped steel arch clamp is used as the positioning of U-shaped steel arch. It requires high force, safety and stability, and is durable and durable. The equipment can be processed and manufactured to meet the requirements, and it has the advantages of material saving, stable molding, high processing efficiency and low investment.

Rock bolt is the most basic part of roadway support in contemporary coal mines, it reinforced the surrounding rock of the roadway, make the surrounding rock support itself. Material: MG335/400/500/600 Size: diameter 18,20,22 mm Price: discussable and based on the quantity of your enquiry This is left-handed rock bolt, if you want konw more about the rock bolt,

Rail press also called welding rail press, welding steel rail fixing device,steel beam rail press, welding clamp, but no matter what do you call, its role is only a kind of fixed rail pressure.Usually welded on the steel i-beam, but sometimes also can be used in steel plates which embedded in concrete. Rail press can be divided into WJK, SWJK, HWJK series TG38, TG43, TG50, TG60, QU70, QU80, QU100, QU120 ,which consists of base, cover, wear of shaw, spring flat washer. With two kinds materials: one kind is half cast steel: cover for nodular cast iron, the base for cast steel. The other is a whole cast steel: top and bottom are cast steel.

Model: threaded bolt Specification: 18*2m, 16*6m (customize according to customer requirement) Material: 16Mn, 20Mnsi Characteristic: 1. The anchorage end and the fastening end do not require machining; 2. The strength is equal all the length, high material utilization; 3. Strong anchoring force; 4. Equipped with prestressed gasket, easy to control installation quality; 5. The installation speed is fast, it is a new type of anchor rod, which is a kind of material that save material and work, equal strength, and the left screw steel bolt has a wide application prospect.
