FAQ

 

   FAQ:

1. What are Plastic Chair Rebar Spacers?
Plastic Chair Rebar Spacers (also called Rebar Supports, Bar Chairs, or Concrete Spacers) are small, durable plastic supports used in reinforced concrete construction. They are placed between the rebar (steel reinforcement) and the formwork to maintain the specified concrete cover - the protective layer of concrete over the steel - ensuring structural integrity, durability, and compliance with building codes.

2. What are the primary applications?
They are essential in all types of reinforced concrete work:

Slabs & Floors (ground slabs, suspended slabs, raft foundations)

Walls & Columns

Beams & Footings

Swimming Pools & Water Tanks

Precast Concrete Elements

Roads, Bridges, and Infrastructure

3. What materials are the spacers made from?
We manufacture spacers from high-quality, engineered plastics:

Polypropylene (PP): Most common, offering excellent chemical resistance and durability.

Reinforced Nylon (PA6/PA66): For higher strength and temperature resistance in demanding applications.

Recycled Material Options: Available for environmentally conscious projects (subject to performance requirements).
All materials are non-corrosive, rust-proof, and chemically inert to ensure they do not react with concrete or steel.

4. How do I choose the correct height (cover size)?
The spacer height equals the required concrete cover specified by the structural engineer or local building code (e.g., ACI 318, Eurocode 2, BS 8110).

Common Heights: Range from 15mm to 100mm+.

Selection: Simply choose a chair with a height matching your required cover (e.g., use a 40mm high chair for a 40mm concrete cover).
We offer a complete range of standard sizes. Custom heights are available for OEM orders.

5. What load capacity do they have?
Our spacers are designed to support the weight of workers and wet concrete without collapsing:

Standard Capacity: Typically 50kg to 200kg+ per spacer, depending on the model and design.

Heavy-Duty Models: Available for high-load applications like deep beams or heavy rebar mats.
Load capacity data is provided in our technical datasheets.

6. What types/models do you offer?
We produce a wide variety to suit different rebar arrangements:

Standard Circular Chairs: Most common for slab work.

High Chairs / Tower Spacers: For deep concrete covers in foundations or walls.

Continuous Line Spacers / Bolster Chairs: For supporting multiple bars in a row.

Wheel/Saucer Spacers: For column/wall reinforcement.

Beam Chairs & Specialty Spacers: For specific structural elements.




Tie-wire Types: For quick attachment to the rebar grid.

7. Are they easy to install?
Yes, installation is quick and requires no tools:

Simply place the spacer on the formwork (or existing concrete).

Position the rebar into the seat/groove of the spacer.

For some models, snap the locking clip or use the integrated tie-wire holes for extra security.
This saves significant labor time compared to traditional wire or stone block methods.

8. Do they leave marks on the finished concrete surface?
Our spacers are designed with a minimal contact footprint. The small legs create only tiny, shallow impressions that are generally acceptable and do not compromise the surface integrity. For architectural finishes, we offer spacers with especially small feet or snap-off legs that break below the surface.

9. What are the advantages over traditional wire/cement block spacers?
Guaranteed Accuracy: Ensures precise, consistent concrete cover.

Non-Corrosive: Will not rust and cause concrete staining or spalling.

Higher Strength: More reliable under load than cement blocks.

Faster Installation: Reduces labor time.

Cost-Effective: When factoring in total labor and material savings.

Safer: No sharp wire ends to cause injuries.

10. Can you provide custom colors?
Yes. We can produce spacers in custom colors for:

Project/Brand Identification: Different colors for different cover sizes or contractors.

Quality Control: Easily visible to inspectors, ensuring proper use.

Aesthetic Blending: For exposed aggregate finishes.
Standard colors are usually black or gray.

11. What is your MOQ (Minimum Order Quantity)?
Standard Items: MOQ 50,000 pieces (can be mixed across standard types/sizes).

Custom Items/OEM: MOQ 200,000 pieces (negotiable based on design).

Samples: Available for testing and approval.

12. What is your production lead time?
Samples: 7-10 working days.

Standard Production: 15-20 working days.

Custom/OEM Production: 25-35 working days after mold/tooling approval.
