Probably the most used depth of Posi-Joist, this 253mm metal web joist allows you to clear larger spans up to 6100mm while reducing or eliminating the need for intermediate load-bearing walls or steel beams. The 159mm flange clearance provides flexibility for modern building designs, allowing large-diameter MVHR ducting, commercial soil stacks and complex plumbing to route through the floor with no drilling or notching. Made to order in our UK factory using specialist MiTek design software, these lightweight joists dramatically speed up floor installations while ensuring compliance with UK Building Regulations.
