Fields of Application
Finishing systems for stainless fabrication and metal construction
Architectural metalwork, railings and structural frames need consistent weld blending, directional satin and clean tube finishes — often on site with limited power and space.
LUPFIGS supplies matched SUHNER electric, battery and pneumatic tools with the right abrasives for tube grinding, fillet-weld blending and decorative satin on stainless and mild steel — helping fabricators deliver uniform results from workshop to installation.
Industry Demands
What metal construction finishing requires
Every railing, frame and weld joint places strict limits on heat discoloration, grain direction and final appearance.
Tube & Profile AccessBelt and flap systems that follow round, square and rectangular sections without flat spots
Weld Blend QualityRemove weld reinforcement and fair fillets without gouging parent metal
Consistent SatinRepeatable directional finishes on rails, panels and visible joints
Heat & DiscolourationCorrect speed and pressure to limit blueing on stainless and thin-wall tube
On-Site MobilityBattery and portable options for installation sites and restricted power access
Typical Work Areas
Where our systems are used
From workshop rail production to on-site weld cleanup, each task needs a different combination of drive, abrasive and reach.
01
Tube & Railing
Grinding and finishing on tubular metalwork
Belt and flap systems for round, square and rectangular tube on handrails, balustrades and structural frames.
Joint Fairing
Blend mitre cuts, copes and welded connections on railing assemblies.
Surface Prep
Clean and refine before passivation, coating or client handover.
02
Fillet Welds
Blending and cleanup on welded joints
Remove weld reinforcement, fair transitions and prepare fillet welds on frames, brackets and structural connections.
Weld Removal
Controlled grinding of excess weld metal without undercut.
Corner Blend
Smooth fillets into parent plate and tube surfaces.
Inspection Ready
Clean, uniform joints suitable for visual and NDT checks.
03
Satin & Decorative
Directional and decorative surface finishes
Architectural stainless needs consistent grain direction on panels, cladding and visible weld zones.
Grain Matching
Align finish direction with existing mill or prior satin work.
Scratch Removal
Blend handling marks and weld heat tint into uniform satin.
Decorative Polish
Step up through grits for specified visual grades on feature metalwork.
04
On-Site Mobile
Portable finishing at installation sites
Site work on staircases, balustrades and frames often means no fixed bench power — battery and compact tools keep progress moving.
Battery Angle Grinders
Cordless grinding and blending where mains power is unavailable.
Compact Belt Tools
Tube and edge finishing in tight installation spaces.
Consumable Supply
Matched discs and belts sized for site work and quick changeover.
Recommended Systems
Tool platforms matched to metal construction
Select the drive and abrasive combination that fits the section size, weld type and required finish.
Electric
Electric Tools
Belt grinders and long-reach tools for workshop tube and weld finishing.
Cordless
Battery Tools
18 V CAS cordless grinders and belts for on-site installation work.
Consumables
Abrasives
Flap discs, belts and fibre discs for stainless and mild steel.
Air Tools
Pneumatic Tools
Production grinders and sanders for high-volume fabrication shops.
Application Approach
Build a controlled metal finishing process
We help fabricators define a clear sequence from weld cleanup through to client-ready satin.
01
Assess Joint
Identify weld type, section size, access and specified finish grade.
02
Match Abrasive
Select disc, belt or flap for material, removal rate and grain direction.
03
Blend Welds
Remove reinforcement and fair fillets without gouging or heat tint.
04
Apply Satin
Work through grits for uniform directional finish on visible surfaces.
05
Inspect & Hand Over
Confirm appearance, clean surfaces and document methods for repeat work.
