Product Overview

Plastic Rebar Ladder Spacers are specially designed plastic supports used to maintain accurate spacing between upper and lower reinforcement layers in concrete slabs or precast elements. They are made of durable, high-strength plastic that resists corrosion and deformation, ensuring stable positioning of the steel reinforcement during concrete pouring.

The ladder-shaped structure provides excellent load-bearing capacity while allowing concrete to flow freely around the reinforcement, ensuring optimal bonding and structural strength.

 

Key Features

1. Material Advantages:

Corrosion-resistant - Ideal for humid, alkaline, or chemically aggressive environments (unlike metal chairs that rust).

Non-conductive - Safe for projects requiring electrical insulation (e.g., power plants, labs). Lightweight & Durable - Easy to handle and install, reducing labor costs.

2. Design Variations:

Available in circular, saddle, stepped, or adjustable designs.

Multiple height options (e.g., 15mm to 100mm) to meet concrete cover thickness requirements.

Some models are stackable for height flexibility.
3. Colors & Identification:

Typically green, blue, or black for easy on-site recognition.

4. Eco-Friendly:

Recyclable material, supporting sustainable construction practices (e.g., LEED-certified projects).
5. Advantages Over Traditional Spacers:

Feature Plastic Rebar Chair Metal/Concrete Spacers.

Durability Resists rust & chemicals Prone to corrosion (metal) / brittle (concrete).

Installation Lightweight, no-tool setup Heavy, requires manual tying.

Cost Efficiency Long-term savings Low up front cost but high maintenance.

6. Technical Considerations:

Select chair height based on design-specified concrete cover depth.

For high-temperature environments (e.g., steam curing), verify plastic heat resistance.

Application

Primary Applications

1. Ensures Proper Rebar Positioning

Maintains consistent concrete cover thickness over rebars, preventing corrosion and structural weakness.

2. Improves Construction Efficiency

Faster installation than wire or concrete spacers, ideal for slabs, beams, columns, and foundations.

3. Common Use Cases

Building Construction (floors, walls, footings).

Infrastructure Projects (bridges, tunnels, dams).

Special Environments (waterproofing projects, chemical plants, hospitals).
