Concrete Plastic Spacers

Description

Concrete Plastic Spacers Manufacturer in China

Plastic spacers for concrete are essential construction accessories designed to maintain the correct distance between reinforcing steel (rebar) and the concrete surface, by positioning the rebar precisely-either vertically or horizontally, depending on the spacer type. Concrete plastic spacers ensure the required concrete cover is achieved. Proper cover protects the reinforcement from corrosion, prevents cracking or spalling, and guarantees the durability of the structure. Once the concrete is poured, the plastic spacers remain as a permanent part of the construction.

Key Features of Concrete Plastic Spacers

High-Strength Materials

Plastic concrete spacers are made from premium polypropylene (PP) or polyethylene (PE), offering high compressive strength and durability to withstand the pressure of concrete pouring. Unlike steel, the plastic material will not rust or deform, making it ideal for use in humid, acidic, or alkaline environments.

Lightweight & Easy Installation

Concrete plastic spacers are lightweight, easy to transport, and simple to install. They reduce construction time and labor costs while ensuring convenient on-site handling.

Available in Multiple Specifications

Our plastic spacers are available in a variety of cover heights and diameters to meet different structural requirements. Whether for slabs, beams, columns, or precast elements, we provide customized spacer sizes tailored to your application.

Environmentally Friendly & Recyclable

Made from recyclable materials, these spacers meet environmental standards and help minimize their environmental impact.

Plastic Spacers Production Process

1. Raw Material Selection: We select high-quality polypropylene (PP) or polyethylene (PE) to ensure strength, durability, and corrosion resistance.

2. Injection Molding: Advanced injection molding machines melt the raw materials and inject them into precision molds, ensuring uniform gasket shape and precise dimensions.

3. Cooling and Demolding: After molding, the gasket is cooled and demolded to maintain the product’s design and performance.

4. Quality Inspection: Each batch of products undergoes rigorous testing for strength, dimensional accuracy, and surface finish to ensure compliance with construction standards.

5. Packaging and Shipping: Only qualified products are packaged and shipped, ensuring customers receive reliable and consistent products.

Applications of Plastic Spacers

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 (including waterproofing projects, chemical plants, and hospitals).

Package of Concrete Plastic Spacers

After passing strict quality inspections, our plastic spacers are neatly packed into durable PP bags. The quantity in each bag varies depending on the type and size of the spacer, making it convenient for both counting and handling. Each bag is securely sealed with cable ties to prevent any loss during transportation. The bags are then carefully stacked and bundled onto strong wooden pallets in fixed quantities, further reinforced with protective film to ensure stability and prevent shifting during long-distance transit. This meticulous packaging process not only improves loading and unloading efficiency but also guarantees that every product arrives at your site in perfect condition. We understand how critical component integrity is for construction projects, which is why we take extra care in packaging, ensuring our plastic spacers are delivered safely, intact, and on time to support your construction needs.
