We can supply all your stair material needs, from stringers to stair treads to risers as well as matching this in with posts and balustrades. When it comes to stairs there is a multitude of variations available for application depending on the structural requirements of the building. The most common type of stair construction is house treads into stringers. Flights may be constructed with ‘open treads’ without risers or ‘closed treads’ with riser boards. Open tread stairs are recommended for external use because they give better air circulations allowing exposed timber to dry more quickly, thus improving durability.
