Floor Joists

We produce floor joists for construction. Block structures are widely used in civil and industrial construction for floors, columnar metalworks as well as for building roofs, bridges, abutments, overhead rails, crane trestles, indoor markets, station houses, etc. Builders employ wood-and-metal joists in load-bearing frames, roof truss structures and interfloor overlapping.

A wood-and-metal joist consists of a weld metal core covered with two wooden plates which are fastened alternately longwise with expandable bushing.

A wood-and-metal joist tempers the best qualities of metal and genuine wood:

Thus, wood-and-metal joists are more competitive in comparison with other kinds of joists.

We can offer You a wide range of wood-and-metal joists with different characteristics and dimensions.
