Firm Grip Stair Tread
A flat step with 9mm punched raised holes to ensure non-slip properties, and a 5mm countersunk hole to drain off water and oil. The stair treads have a specially designed front edge to provide excellent strength; on 30mm width an additional hole to provide an extra fixing point.
These stair treads are designed according to British Standard BS4592 Part 3 1987.
