The 32mm Stainless Steel Centre Brackets are engineered for heavy-duty mid-span support of 32mm round tubes, targeting industrial, marine, and high-demand commercial projects. Crafted from 316L stainless steel—the gold standard for extreme environments—these brackets resist saltwater, chemicals, and extreme temperatures (-50°C to 250°C), making them ideal for offshore platforms, factory conveyor systems, or coastal construction.

With a 110 lbs (50 kg) load capacity, they outperform 25mm brackets by 43%, supporting heavy machinery parts, bulk inventory, or marine equipment. Unlike standard brackets, they feature radiographed welds (100% inspection) and a 3mm-thick steel gauge, eliminating hidden defects and ensuring durability in high-vibration environments (e.g., manufacturing plants). The closed-top tube cradle secures the 32mm tube in place, preventing slippage even during equipment operation. Meeting ASTM A815 Class WP-W standards, these brackets are a reliable choice for projects where safety and longevity are non-negotiable.
• Material: 316L stainless steel (2-3% molybdenum content; compliant with EN 10088-2)
• Tube Compatibility: Exclusively for 32mm outer-diameter round tubes (tolerance: ±0.05mm)
• Load Capacity: Up to 110 lbs (50 kg) per bracket (steel/concrete); 88 lbs (40 kg) (wood studs)
• Dimensions: (L) 280mm × (H) 35mm × (Thickness) 3mm (heavy-duty gauge)
• Mounting Type: Triple-hole design (M8 × 40mm stainless steel bolts, 35mm center-to-center spacing)
• Finish: Mill-finished stainless steel (industrial-grade; resists scratches from heavy tools)
• Testing: Passes 1,000-hour salt spray testing (ISO 9227); 1,000-hour UV exposure testing (ISO 105-B02)
• Compliance: ASTM A815 Class WP-W (radiographed welds); OSHA load-bearing safety factor of 2.5
• Marine-Grade Corrosion Resistance: 316L stainless steel’s molybdenum content makes it 4× more resistant to pitting than 304 steel, withstanding saltwater (3.5% salinity), industrial acids (sulfuric acid up to 5%), and harsh cleaning agents. It’s ideal for boat decks, docks, or chemical plants.
• Industrial-Grade Load Capacity: The 110 lbs rating supports heavy items like factory tooling, 50lb inventory boxes, or marine winch components. The 3mm-thick steel gauge prevents bending even under maximum load.
• Vibration-Resistant Closed Cradle: The closed-top design (unlike open-top brackets) secures the 32mm tube in place during vibration (e.g., conveyor systems, construction equipment). No risk of tube slippage during operation.
• Extreme Temperature Tolerance: Functions reliably from -50°C (cold storage facilities) to 250°C (industrial ovens), maintaining strength and corrosion resistance across temperature fluctuations.
• Radiographed Welds: Every weld undergoes X-ray inspection to detect hidden defects (porosity, cracks), ensuring 100% integrity. This meets industrial safety standards for high-risk applications.
• Universal Mounting: Works on steel, concrete, or wood surfaces. For concrete, use M8 masonry anchors (sold separately) rated for 110 lbs.
Perfect for extreme or high-stakes environments:
• Industrial Settings: Conveyor system rails (automotive manufacturing), machinery support tubes (food processing plants), and pipe racks (chemical facilities).
• Marine Use: Boat hull rails, dock equipment (cleat supports), and offshore platform safety rails (resists saltwater corrosion).
• Commercial Heavy Use: Warehouse inventory racks (50lb boxes), retail furniture display frames (heavy items like sofas), and gym equipment supports (weight racks).
• Coastal Construction: Boardwalk railings, beachfront property fences, and outdoor kitchen grill supports (resists salt air).
Q: Why is 316L stainless steel better than 304 for this bracket?
A: 316L contains molybdenum, which forms a stronger protective oxide layer than 304. It’s 4× more resistant to pitting corrosion—critical for marine or industrial environments where 304 would rust within 1-2 years.
Q: What’s the maximum span a 32mm tube can have with these brackets?
A: For 32mm stainless steel tubes, space brackets every 1.2m (4ft) to maintain the 110 lbs load capacity. A 4m span requires 3 center brackets (one every 1.2m) plus end supports. For aluminum tubes (less rigid), reduce spacing to 1m.
Q: Can these brackets be welded to a steel beam?
A: Yes—use TIG welding with ER316L filler rod to match the bracket material. Post-weld annealing (heating to 1,050°C and cooling slowly) is recommended to reduce weld stress and maintain corrosion resistance.
