Stainless Steel Or Galvanized Steel Tile Backer Board Washer 28mm, 32mm, 36mm, 38mm For Fixing Rigid Insulation Board

This galvanized steel washers or stainless steel washers, also could be called tile backer board washers, which are made from galvanized steel / stainless steel 430 / stainless steel 410 / stainless steel 304 materials, the type could be tabbed or flat, the size could be 28mm, 32mm, 36mm, 38mm etc.

This tile backer board washer could be used to fasten kinds of rigid foam board, such as EPS Board, XPS Board, Polyurethane Foam Board, Glass Wool Board, Phenolic Foam Board.

We supply the steel washers for many years, the material, the size, the type, the package, and the logo all is customizable based on your need.

Product Overview:

When installing tile backer boards or rigid insulation panels, a secure and reliable fastening system is critical to prevent tile cracks and substrate failure. Our Tile Backer Board Washers-available in Stainless Steel and Galvanized Steel, and in four precision diameters (28mm, 32mm, 36mm, and 38mm)-are the ultimate solution for fixing rigid insulation boards, cement backer boards, and foam panels. Engineered to provide maximum holding power and load distribution, these washers ensure your substrate stays perfectly anchored to the wall or floor studs, creating a flat, stable, and long-lasting base for tile, stone, or plaster finishes.

Key Features & Benefits:

• Dual Material Options for Every Environment:

• Stainless Steel: The premium choice for high-humidity and wet areas such as showers, steam rooms, and swimming pools. Offers unmatched corrosion resistance, ensuring the washers will never rust and compromise your tile work.

• Galvanized Steel: A highly cost-effective alternative for standard interior and dry areas. The zinc coating provides excellent protection against oxidation, making it ideal for general residential and commercial construction.

• Four Precision Diameters (28mm, 32mm, 36mm, 38mm): We offer a full range of sizes to match different board thicknesses and screw specifications. The larger diameters (36mm, 38mm) provide extra bearing surface for softer insulation boards, while the smaller sizes (28mm, 32mm) are perfect for tighter stud spacing or thinner cement boards.

• Superior Load Distribution: The wide, flat surface of the washer distributes the clamping force of the fastener over a larger area. This prevents screw heads from sinking into or tearing through rigid insulation boards, cement backer boards (like Hardy Backer or Durock), and plasterboards, dramatically reducing the risk of loose tiles.

• Flush & Professional Finish: Designed with a flat or slightly cupped profile, these washers sit flush against the board surface once screwed in. This guarantees a smooth, even substrate for tile adhesion, preventing lippage, uneven surfaces, or grout cracks.

• Easy & Efficient Installation: Simply place the washer over a suitable wood or masonry screw and drive it through the board into the stud or substrate. The burr-free edges protect the board facing from damage, allowing for rapid installation on large-scale projects.

  
  

Typical Applications:

• Tile Backer Board Installation: Securing cement boards, fiber cement boards, and glass-mesh reinforced boards in bathrooms, kitchens, and wet rooms.

• Rigid Insulation Board Fixing: Fastening XPS, EPS, PIR, and phenolic foam boards to walls and floors before tiling or plastering.

• Underfloor Heating Systems: Anchoring insulation layers and tile backer boards over concrete subfloors to improve thermal efficiency.

• Exterior Insulation and Finish Systems (EIFS): Providing a mechanical fix for rigid foam insulation on external walls.

• General Construction & Renovation: Any project requiring a robust, wide-bearing washer for panel or board fixation.
