Nut, Coupling, Plate, Centralizer, Cross drill bit, Button drill bit and Clay bit can be supplied by different sizes. They can also be supplied according to the drawing or specific requirement.
Hollow bar anchor is pull rod that transfer anchored structures or geotechnical loads to a stable formation. Pressure grouting of the anchor bar through the hollow bar body can achieve the purpose of consolidating the broken rock mass, blocking the groundwater and the anti-corrosion of the rod body, and rapidly forming the supporting force to control the stability of the surrounding rock.
The product is composed by hollow anchor bar, anchor nut, anchor plate, anchor coupler, drill bit, and the hollow anchor bars can be cut and lengthened by coupling on request. It is unique anchoring system and can meet current and increasing demands of the tunneling industry and ground engineering.
Post-tensioned unbonded prestressed concrete steel strands are used for cast-in-situ floor slabs of large-span and large-bay buildings, prefabricated beams with large loads, and other special structures and special constructions. It has the characteristics of no need to leave holes, no grouting, simple construction, material saving, and random bending.
The application of prestressed conctete steel wire is for super-tall, super-span, super-volume, super-large area and overweight load engineerings of single storey and multi storey houses, highway and railway bridges, sleepers, electric poles, pressure water pipes, storage tanks, and water towers, expanding to modern high rise buildings, underground buildings, high rise structures, etc.
PC strands are for prestressed concrete structure reinforced, such as large-span bridges on railway and highway, overhead crane beam, rock-soil anchoring project, multi-storey industrial buildings, stadiums, coal mines and etc. We offer PC Strand which confirm to the technical standards such as GB/T 5224, ASTM A-416, BS 5896, JIS G3536 or the standards agreed by both of the customers and us.
Our Friction Bolt is a threaded anchor bolt system designed for underground engineering support. This Friction Bolts Mining support system is commonly used in underground mining, tunnels, and other engineering endeavors, offering robust geological support to prevent rock collapses and soil instability.
Mining cable bolt for roadway support under ground could be 19 wire pc strand , in the field of mine rock reinforcement the Seale type structure is widely used because of its high tensile strength and process easiness compare with traditional bolts.
Wedge pins are used with flat tie to tighten adjoining concrete forms, securing the flat tie and concrete form in place.
