Overview


The Square Expansion Tank Bracket Steel 40×40 is a compact, cost-effective solution designed for secure mounting of medium-sized expansion tanks (5-80L) in residential and light commercial hydronic systems. Engineered with a space-efficient square tubing design, this bracket optimizes limited mechanical room space while providing reliable support for everyday heating applications.


Features


Compact & Sturdy Design:

40×40×2mm Q235B steel tubing supports 120kg static load and 80kg dynamic load, with a 20% smaller footprint than round brackets (depth ≤120mm).

Adjustable mounting plate (50mm vertical travel) fits tanks with 120×120mm mounting patterns, including popular brands like Viega and Taco.

Corrosion & Noise Control:

Electro-galvanized finish (50μm) with epoxy topcoat (RAL 7035), resisting 500 hours salt spray and moderate humidity (RH ≤75%), ensuring 10+ years of service.

2mm rubber isolation pads reduce mechanical noise by 15dB and prevent tank surface abrasion in residential settings.

Easy Installation:

Pre-assembled with M6 bolts, wall anchors, and clear instructions, reducing installation time to 15 minutes—30% faster than custom solutions.

Flat-back design hugs walls tightly (clearance ≤20mm), ideal for closets, under-stair spaces, and RV utility compartments.

Compliance & Safety:

Meets EN 13816 and ASME BPVC Section VIII, with load tested at 130% of rated capacity and fire-retardant coating (UL 94 V-0) for boiler room use.

UV-stabilized finish for limited outdoor use (e.g., protected balconies), with optional anti-vibration mounts for pump-heavy systems.


Application

Apartment Complexes: Supports 20-80L tanks in multi-unit hydronic systems, with sleek design suitable for visible installations in utility rooms.

Light Commercial Offices: Mounts tanks in 20-100kW boiler systems for small commercial spaces, compliant with ASHRAE 90.1 energy standards.

Renovation Projects: Retrofits older homes with undersized mechanical rooms, offering adjustable arms for off-center tank placements.
