Pin-type adjustable steel prop is a fast-locking telescopic support for construction formwork. Made of Q235B/Q345B steel with painted or galvanized surface. It adopts pin positioning structure for quick height adjustment and locking, featuring simple operation, stable bearing and high efficiency. Widely used in concrete formwork shoring, floor beam support, building reconstruction and temporary load-bearing projects. Pin-type adjustable steel prop is a new generation of rapid adjustment temporary steel support, widely matched with modern formwork systems in construction industry. Different from traditional threaded props, this product uses pin hole positioning and safety pin locking structure, which realizes fast height adjustment and instant fixation without rotating nuts repeatedly. It greatly saves on-site operation time and effectively improves construction progress, becoming an ideal supporting tool for high-efficiency construction projects. The whole prop consists of outer tube, inner tube, positioning pin holes, safety lock pin, top plate and base plate. We select high-quality Q235B carbon steel as standard material, and Q345B high-strength steel is optional for heavy load conditions. Both inner and outer tubes are processed by high-frequency welding or seamless pipe, with uniform wall thickness and excellent compression resistance. The dense pin holes are precisely punched on the inner tube with equal spacing, ensuring accurate height gear adjustment and uniform force bearing at each position. All connecting parts between pipe body and end plates adopt full penetration welding, with smooth and firm welds, no cracking or deformation under long-term heavy pressure. Standard outer tube diameters include 48mm, 56mm and 60mm, and wall thickness ranges from 1.8mm to 3.5mm to cover light, medium and heavy load grades. The adjustable height ranges from 1.5m to 5.8m, meeting the height requirements of most indoor floors, beams, slabs and foundation formwork. For surface treatment, we provide anti-rust painting, pre-galvanizing and hot-dip galvanizing. Painted type is economical for short-term use, while galvanized products have superior anti-corrosion performance, suitable for repeated use in humid, outdoor and harsh environments. The safety lock pin is made of thickened solid steel, which can be inserted into the pin hole quickly to fix the inner tube firmly. It effectively prevents accidental retraction and displacement, ensuring overall structural stability and construction safety. This prop has reasonable force distribution, strong anti-bending performance and long service life, and can be reused many times. All products have passed professional compression test and mechanical performance test, complying with international construction temporary support standards. It is widely applied in cast-in-place concrete formwork support, building beam and slab shoring, tunnel formwork, temporary support for renovation and demolition works. With simple structure, lightweight body and convenient transportation and stacking, pin-type steel props are deeply favored by construction teams and formwork rental companies. We adopt standard export packaging with steel strapping to avoid damage during long-distance transportation. With reliable quality, fast adjustment and competitive cost, our pin-type adjustable steel props are exported to many countries and regions.
