When sensitive or heavy equipment needs a stable, distortion-free mounting platform, our X-reinforced square support bases deliver. The four-column frame with X-type diagonal bracing distributes loads evenly across the structure, while post-weld stress-relief annealing keeps the top plate flat and dimensionally stable - a critical detail for precision instruments and electrical equipment.
Key Features
Four columns + X-type bracing: even load distribution with no frame racking or top-plate deformation under full rated load.
Pre-drilled top mounting holes: bolt patterns machined to your equipment footprint - direct drop-in installation.
Adjustable levelling feet: bottom-mounted levelling bolts compensate for uneven floors and allow precise height alignment.
Stress-relief annealing: post-weld heat treatment removes residual stress, protecting flatness and dimensional accuracy over time.
Typical Applications
Data centre UPS battery cabinets and rack systems
Laboratory precision instruments and test equipment
Power transformers and switchgear
Automated production line machinery

Frequently Asked Questions
Q1: What load ratings can you engineer?
We build bases from 500 kg up to 5 tonnes. Tell us your equipment weight plus any dynamic or seismic requirements, and we will size the columns, bracing and top plate accordingly.
Q2: Can you drill the top plate to our bolt pattern?
Yes. Send the mounting-hole layout from your equipment manual or a footprint drawing, and we will machine the top plate to match - direct drop-in installation with no site drilling.
Q3: Why does stress-relief annealing matter?
Welding leaves residual stress inside the steel that can slowly warp the frame and pull the top plate out of flat. Post-weld annealing removes this stress, keeping precision equipment level for years.
Q4: Should we choose powder coating or galvanizing?
Powder coating suits indoor environments such as data centres and labs, with custom colours available. Hot-dip galvanizing is better for humid or outdoor locations.
Q5: Can the base isolate vibration?
Yes. We can fit anti-vibration rubber pads between the top plate and frame for rotating or vibration-sensitive equipment.
