Why Lonsdale is a hub for metal fabrication in South Australia
Grating Industries is a family-run metal fabrication specialist based in Lonsdale, South Australia. From our workshop, we design and manufacture custom steel grating and drainage products for civil, commercial, and industrial construction projects across Adelaide and regional SA. This metal fabrication lonsdale service explains how local fabrication supports compliant, durable drainage and grating outcomes for construction professionals.
Lonsdale is a major industrial hub in South Australia, positioned in Adelaide’s southern corridor with direct access to arterial roads. For construction projects, sourcing grating and drainage components from a local Lonsdale fabricator brings tangible advantages. Transport distances are shorter, meaning reduced freight costs and less risk of damage in transit, plus direct communication and face-to-face project management.

Why Lonsdale businesses choose Grating Industries
Local expertise
Established in 1989 with over three decades of experience in SA construction. Our Heath Street workshop is purpose-built for engineered grating and drainage fabrication, not general metalwork.
Australian Standards compliance
All products are designed and fabricated to meet AS 3996:2019, AS 1657:2018, and AS/NZS 4680. Quality control ensures verified dimensional accuracy and compliance documentation.
Custom engineering solutions
We engineer and fabricate bespoke sizes, shapes, and load ratings that standard catalogue products cannot accommodate, tailored precisely to your project requirements.
Material flexibility
We work with structural steel, mild steel, stainless steel, and specialty materials. Grade selection matches your site conditions, corrosion exposure, and lifecycle expectations.
Frequently asked questions — metal fabrication lonsdale
Grating Industries specialises in custom steel grating, drainage products, trench grates, sump grates, box drains, grated pits, and footpath crossovers. Services include cutting, welding, forming, assembly, and surface finishing. We fabricate for civil, commercial, and industrial construction projects across Adelaide and regional SA.
Yes. All products meet relevant Australian Standards including AS 3996:2019 for access covers and grates, AS 1657:2018 for fixed platforms and walkways, and AS/NZS 4680 for hot-dip galvanising. Load class considerations from Class A to Class D guide design for pedestrian, vehicular, and industrial applications.
Stainless steel is recommended for coastal sites, food facilities, and chemical plants. Grade 304 suits inland or less aggressive conditions, while Grade 316 with molybdenum is specified for marine-adjacent locations and chemical exposure zones. Hot-dip galvanised mild steel works well for moderate outdoor exposure.
The process includes consultation and planning, workshop fabrication, assembly, surface finishing, quality control, and delivery. Timeline depends on project complexity, material selection, and load class requirements. Contact Grating Industries directly for a specific quote and delivery estimate on your project.
