02 · System anatomy
The material is not a single surface.
Mild-steel furniture protected by pretreatment and matte black powder coating, commonly RAL 9005. Edge geometry, weld sealing and exposure-specific coating build determine corrosion life.
01Decorative top surface
Layer function
Polish, patina, plating, PVD, clear coat or powder establishes colour, gloss and touch response.
How to verify
Name the exact finish route, product/layer build and brushing direction.
02Pretreatment / undercoat
Layer function
Cleaning, conversion coating, strike layers or primers create adhesion and corrosion resistance.
How to verify
Require process declaration and adhesion/corrosion evidence for the exposure.
03Base metal
Layer function
Stainless, mild steel, brass, bronze, copper or aluminium determines strength, corrosion and repair.
How to verify
Mill/material certificate or explicit alloy/substrate declaration.
04Fabrication / joint
Layer function
Tube/plate thickness, welds, braze, fasteners, drains and isolators control structural and corrosion performance.
How to verify
Shop drawings and first-off expose welds, inside returns, edges and dissimilar-metal interfaces.

GCC exposure matrix and maintenance plan.
Material-specific climate warning
Exterior/coastal use requires approved exterior chemistry or duplex system; interior epoxy-rich powder can chalk.
01Conditioned interior
Preferred- Material response
- Most declared decorative systems can perform when cleaning is controlled.
- Design control
- Select by touch, wear and repair route; keep one finish process.
02High-touch public area
Conditional- Material response
- Fingerprints, skin oils, rings and repeated wiping reveal coating weakness.
- Design control

03F&B / chemical cleaning
Conditional- Material response
- Acids, chlorides, degreasers and standing liquids attack finish and joints.
- Design control
- Name chemicals and protect horizontal traps, welds and dissimilar metals.
04Wet interior
Conditional- Material response
- Condensation and trapped moisture start at cut edges, fasteners and unsealed tubes.
- Design control
- Use suitable alloy/system, seal/drain cavities and isolate metals.
05Covered exterior
Conditional- Material response
- Sheltered surfaces may retain salt and dirt because rain does not wash them.
- Design control
- Select exterior system and specify accessible routine washing.
06Coastal exterior
Avoid- Material response
- Chlorides, crevices, rough finishes and insufficient cleaning increase pitting/tea staining risk.
- Design control
- Evaluate 316/appropriate alloy or duplex system, smooth finish, drainage and maintenance.

This material-specific application image shows Matte Black Steel Furniture on its own product and is not reused by any other material page. Final colour, pattern and finish remain subject to the approved physical sample.
Project notes
From sample to production.
01
What to specify
Specify both the base metal and decorative finish. “Brass finish” may mean solid brass, brass-plated steel, PVD stainless or paint; performance and cost differ substantially.
02
Fabrication & detailing
Coordinate weld locations, wall thickness, drainage, concealed fixings and dissimilar-metal isolation. Complete grinding and polishing before the final decorative coating.
03
Colour & finish approval
A signed metal control sample defines tone, texture, gloss and brushing direction. Large fabricated pieces can read differently from small chips, so full-size samples may be requested.
04
Care & maintenance
Clean with a soft cloth and mild neutral detergent, then dry. Avoid abrasives, chloride cleaners and aggressive polish; coastal pieces require more frequent fresh-water cleaning.
Specification note
This page is a preliminary specification guide. No value, brand reference or material name constitutes automatic compliance. Current product data, test reports, physical sample or slab and the furniture construction must be approved for each project before ordering or manufacture.
