The Double Fix Spacer is a solid, lightweight, and durable component made from engineered plastics such as Polypropylene (PP) or High-Density Polyethylene (HDPE). Manufactured through plastic injection molding, it features a specialized design that ensures structural stability and even pressure distribution. Thanks to its robust construction, the spacer can support the weight of rebar and concrete without deformation.
Designed for professional-grade applications, the Double Fix Spacer is suitable for various structural uses—including walls, ceilings, and floors—and is typically available in sizes ranging from 2 to 7 centimeters, depending on project requirements.
From a chemical standpoint, the Double Fix Spacer is highly resistant to:
Its polymeric structure remains stable and does not corrode or react chemically when in contact with concrete. To enhance its durability against sunlight exposure and prevent brittleness, additives such as UV stabilizers and thermal protectants are incorporated into the material.
Under normal working conditions, the spacer is non-toxic and safe to handle. However, like most plastics, it is non-biodegradable and remains in the environment unless properly disposed of.
These spacers maintain full stability at ambient temperatures and only begin to soften or degrade at elevated temperatures above 130–150°C. Their mechanical design ensures reliable performance even in heavy concrete pours and industrial-scale construction projects.
To ensure proper installation and optimal performance of the Double Fix Plastic Spacer, follow these steps:
Begin by sliding the head section of the spacer into the groove of the base section until fully inserted. This completes the assembly and prepares the spacer for installation.
Position the lower layer of rebar mesh onto the base. Note that the height of the two wings on the base differs from the other two, allowing for crosswise placement of rebar without interference.
Once the lower mesh is in place, insert the upper layer of rebar into the clamps of the head section. This ensures secure positioning and stability of the upper mesh.
By following these steps, you can effectively use Double Fix Plastic Spacers for reinforcing concrete slabs with dual rebar layers, ensuring high-quality and precise execution in your construction projects.
To maximize the effectiveness of Double Fix Spacers, consider the following:
Double Fix Spacers are designed for concrete slabs and floors with relatively high thickness that require two layers of reinforcement mesh. They are especially useful for dual-mesh slab reinforcement.
Typically, 4 Double Fix Spacers per square meter are used. However, the exact number should be determined based on:
After calculating the weight of the rebar structure and considering the applied loads:
By adhering to these guidelines, you can ensure effective use of Double Fix Spacers and achieve reliable reinforcement and load distribution in your concrete projects.
