Holderbat Galv Group

The Galvanized Holderbat is a professional-grade structural bracket engineered for the South African construction, plumbing, and DIY sectors. Designed to provide a rigid, non-slip anchor point, it is the primary choice for fastening galvanized, PVC, or copper piping and rainwater downpipes to masonry walls. Manufactured from hot-dipped galvanized steel, these brackets are specifically built to resist the corrosive effects of South African coastal air and the frequent wet-dry cycles of the Highveld, ensuring your piping systems remain stable and correctly aligned for decades.

Key Performance Features

• Hot-Dipped Galvanized Coating: Provides a robust, rust-resistant barrier that protects the core steel from moisture and oxidation—essential for both indoor plumbing and exposed outdoor drainage.
• Heavy-Duty Clamping Action: Features a two-piece bolt-together design (often with 6x20mm gutter bolts) that provides a high-friction grip on the pipe, preventing vertical “slippage.”
• Integrated Wall Spike / Top-Hat Screw: Equipped with either a sharp masonry spike for “wet-setting” into mortar or a threaded screw for direct anchoring into wall plugs.
• Malleable Steel Construction: The bracket arms are engineered to have a degree of flexibility, allowing for slight adjustments during installation to ensure perfect pipe verticality.

Ideal Applications

• Rainwater Downpipe Mounting: The industry standard for securing square (100x75mm) or round (75mm/110mm) galvanized and PVC downpipes to residential and industrial buildings.
• Surface-Mounted Plumbing: Perfect for securing 15mm to 50mm galvanized or copper water supply lines along external walls or in plant rooms.
• Agricultural Standpipes: Ideal for providing structural stability to 1/2″ and 3/4″ standpipes in livestock camps and garden irrigation points.
• Waste & Soil Pipe Support: A reliable primary bracket for 40mm and 50mm waste pipes in residential bathrooms and kitchens.

Product Benefits

• Superior Load-Bearing Stability: Designed to carry the weight of full water columns without sagging, protecting your pipe joints from mechanical stress.
• Serviceable Design: The bolt-together clamp allows for the easy removal or replacement of the pipe for maintenance without having to remove the bracket from the wall.
• Professional Aesthetic: Provides a neat, uniform finish that aligns with South African building standards for visible exterior plumbing.

Pro Tip: For a standard 2.7m downpipe, it is recommended to use at least two holderbats to prevent vibration and wind-rattle. When installing in coastal regions like the Western Cape or KZN, consider painting the galvanized bracket with a high-quality Acrylic PVA or Cold Galv spray for an additional layer of salt-spray protection. Installation Note: Ensure the wall spike is properly sealed with cement or specialized epoxy to prevent moisture from seeping into the brickwork.
