Rebar chairs or Metal Rebar Chairs as they are also known are used in military applications, road construction and for making castors. Chairs made from rebar are tough, reliable and long lasting. They can withstand heavy loads and can withstand harsh environmental conditions. Their material is strong and durable, and their design makes it ideal for use in various application areas. They are usually portable in nature and can be transported even though some manufacturers recommend that they are not to be used outside the building where they are used.
Rebar Metal Reinforced rebar chairs are commonly used in road construction and highway repair. PVC/PSF rebar chairs are specially designed to withstand both tensile and compressive stresses. These chairs have a high tolerance to chemicals and acids and a sufficiently long life span.
Plastic Rebar Metal reinforcement, consisting of polystyrene, is used to make rebar chairs as well as a number of other applications. A PVC backing is included in the plastic components to create the required tensile strength. The plastic forms are then welded to the steel frames to form the necessary framework. This allows the framework to expand or contract according to the application and to provide extra strength. This is the reason why rebar chairs have a long useful life span.
The basic design of rebar chairs is such that they have either round caps or flat cover caps. The round cap design makes it easy to add stakes to the top of the chair with a very simple process. The flat cover caps prevent the stakes from rolling off the bottom as they are rolled towards the top. The plastic feet fitted over the steel frames allow the user to stand on top of the framework while working on concrete or other hard surfaces. This helps improve safety on the job.
These types of rebar chairs require no special welding skills. The PVC pipes used to form the body of the chair are fitted onto steel rebar frames. Simple holes are drilled into the frame to allow a bolt or screw to be fed through to secure the frame. Additional holes are drilled for screws to be added to support the upper legs of the chair. Concrete reinforcement is added at the front, back and underside of the seat to strengthen the whole unit.
Plastic rebar chairs and other products made out of rebar are strong and durable. They do not rust and require little maintenance. Their low price and high durability make them ideal for construction sites and road repairs. Plastic rebar reinforced concrete chairs also help to save fuel and labor cost, making them more economic than other types of steel rebar chairs.
