Description
Punching Shear Resistance Studs (PSR) are large headed punching shear connectors that are welded to flat steel bars (creating stud rails) and are used as punching shear reinforcement in flat concrete slabs to replace abutment stirrups and column capitals and resist punching stress in the slabs. Uprights of predetermined length and diameter, as per design specifications in accordance with IBC and UBC structural steel welding standards, are used to extend the perimeter of the column in the floor slab or foundation slab. This reduces the amount of rebar required in an area and column congestion, resulting in easier and faster installation and lower cost. By using these punching resistance beams, the punching capacity at the base of the concrete columns is increased, resulting in a significant reduction in slab thickness. This results in substantial savings in labour and material costs.
Material: Low carbon steel, ASTM A29/A108, 1010-1020

Our Company
China IKING Industrial co.,Ltd
1.We choose the quality mild carbon steel(SWRCH18A) from Xingtai Steel Factory.
2.We do phosphorization pretreatment for the raw material using drawing machine.
3.We purchase the multi-station cold forging machine from the biggest factory in Zhejiang Province to ensure the better mechanical property of PSR to match the standard(BS EN ISO13918:2008, AWS D1.1, etc.), or as per customer's special requirement.
4.We use the automatic riveting machine to install aluminum ball on the end.
5.After rust prevention, IKING's PSR can suitable for long time ship on the sea.
6.Short delivery time because of our reasonable production flow management
