Plastic space block for protective layer of reinforcing steel bar is designed according to the requirement of national steel concrete construal design norm. It is widely applied in the civil and industrial construction of buildings, roads, bridges, tunnels, airports, subway and so on. And the clip style spacer usually used in the bevel of the construction. Clip plastic special use at the inclined plane.
Product Character: Having the advantages of high bearing capacity, self locking, crash-proof, good coherence, and easy operation. It is free from the potential quality problems of instable thickness of the protective layer resulting form the use of traditional materials of coprolites and sands.

What are plastic spacers used for?
Plastic spacers are used with reinforcement products. The spacers allow the reinforcement steel to be positioned in the required locations. This can be vertically or horizontally (dependent on type). The space required for mesh and rebar is determined by the requirements of the concrete slab and specification provided by a structural engineer.
Why use plastic spacers?
Plastic has been found to be one of the most versatile of all building materials. In precast technology it has a major role to play in the maintenance of cover in precast units. It is mandatory to maintain a specific spacing between the reinforcement and the slab face. The variety of precast units has led to a significant array of plastic solutions being developed, each with characteristics which makes them adapt to specific applications.
