The Square Expansion Tank Bracket Kit Steel 40×40 is a versatile, cost-effective solution designed for secure mounting of expansion tanks in residential hydronic systems, particularly suited for retrofitting older homes and small commercial spaces. Engineered with a modular steel frame and adjustable components, this kit balances affordability with reliability, ideal for contractors and DIY enthusiasts seeking a straightforward mounting solution.
Retrofit-Optimized Design:
40×40×2mm Q235B steel tubing supports 100kg static load and 70kg dynamic load, with adjustable mounting arms (50mm vertical travel) to fit tanks from 5L to 60L—perfect for mismatched tank sizes in older systems.
Kit includes main bracket, mounting hardware (M6 bolts, wall anchors), and shims for uneven walls, reducing retrofit installation time by 40% compared to custom brackets.
Corrosion & Wear Resistance:
Electro-galvanized finish (50μm) with acrylic topcoat (RAL 9005 black), resisting 500 hours salt spray and moderate humidity (RH ≤80%), suitable for basements and utility rooms.
3mm felt pads prevent tank surface scratches during adjustment, critical for protecting vintage or painted tanks.
Universal Fit:
40mm square tube compatibility with standard 100x100mm mounting patterns (Viega, Taco), supporting both vertical tanks and horizontal accumulators with included swivel brackets.
Pre-drilled for wood studs and metal tracks, with a slim profile (depth 120mm) fitting into 150mm-thick walls common in older constructions.
Compliance & Safety:
Meets EN 13816 and ASME BPVC Section VIII, with load tested at 120% of rated capacity and clear installation diagrams compliant with IPC 2021 residential codes.
Lightweight (2.8kg) and easy to handle, reducing risks during overhead installations in attics and crawlspaces.
Suited for residential retrofits and small-scale systems, this bracket kit is used in:
Older Home Renovations: Retrofits 5-30L tanks in homes with outdated mechanical rooms, offering adjustable arms to align with non-standard joist spacing.
Small Commercial Retrofits: Supports 20-60L tanks in converted retail spaces or offices, with budget-friendly design without compromising safety.
Garage & Workshop Heating: Secures tanks in standalone boilers for garage radiant floors, with corrosion-resistant finish suitable for moderate tool storage environments.
Mobile Home Upgrades: Used in RV and mobile home retrofits, with lightweight design and vibration resistance compliant with RVIA standards.
Q: Can this bracket be installed on plaster walls?
A: Yes, use the included hollow-wall anchors; for solid masonry, drill and use concrete anchors (not included, available locally).
Q: What is the difference between this kit and the industrial square bracket?
A: This kit is optimized for residential retrofits (lower load rating, budget finish), while the industrial version offers higher load capacity and extreme environment resistance.
Q: Are the mounting arms removable for custom configurations?
A: Yes, arms can be detached and repositioned using the included bolts, allowing unique mounting angles for irregular spaces.
