Reinforcing Bar Support – Bar Chairs and Metal Bolsters

There are three bar chairs of different sizes with white plastic coating, and the large size chair is on a round black plate.

With high strength and good stability, reinforcing bar support is perfect for reinforcement bars supporting in concrete structure.

Reinforcing bar supports are made of high quality carbon steel or stainless steel. They have galvanized surface, including bar chair and metal bolster, and there are various types and sizes for choice. With high strength, rigidity and stability, they can greatly save the working time and they're widely used to support reinforcement bars at determined heights for construction project. Reinforcement tie wires are also necessary to secure reinforcement bars in place until the concrete is poured.
