In today’s fast-moving industrial landscape, reliable, high-quality steel processing is more than just a support service, it’s a critical foundation for successful projects. From large-scale construction to mining, infrastructure, and agriculture, Cornwall’s industries demand steel that performs, lasts, and arrives on time.
At Hewaswater Engineering, we’ve been meeting those needs for over 75 years, delivering precision steel processing services tailored to the region’s diverse sectors. Here’s how we support the modern industry across Cornwall and the South West.
What Is Steel Processing?
Steel processing involves transforming raw or semi-finished steel into fabricated components ready for use in structural frames, buildings, equipment, and more. This includes:
- Cutting
- Drilling and punching
- Welding and fabrication
- Surface preparation (shot blast & paint)
- Assembly and delivery
At Hewaswater, we manage the entire process in-house, using advanced machinery and experienced hands to ensure every piece is made to spec and ready to perform.
Supporting Key Industries in Cornwall
Mining & Aggregates
Cornwall’s rich mining heritage continues today through operators like Imerys and Aggregate Industries. We provide robust steel components, support frames, hoppers, and conveyor systems built for heavy-duty use in abrasive and corrosive conditions.
Construction & Infrastructure
From rural barns to multi-storey buildings, our processed steel is used in everything from portal frames to bespoke architectural elements. Our CNC drill and saw lines ensure accuracy and efficiency, while our fabrication teams can handle everything from one-off beams to full structural packages.
Agriculture & Rural Buildings
Farm buildings need strong, durable steel that can withstand both weather and wear. We supply structural sections, steel cladding rails, and complete frames for barns, sheds, and machinery housing.
Marine & Coastal Projects
Cornwall’s marine environment demands steel that can resist rust and salt damage. Our shot blasting and paint services add the essential protection needed for coastal infrastructure and equipment.
Meeting Modern Demands with Modern Tools
We invest in technology that gives our clients the edge. Our Peddinghaus CNC lines, heavy-duty handling equipment, and specialist fabrication facilities allow us to process steel with:
- High speed
- Tight tolerances
- Low material waste
- Reliable repeatability
This means we can take on both high-volume and bespoke projects, delivering consistently, even under tight deadlines.
Why In-House Steel Processing Matters
Unlike many suppliers who outsource fabrication or finishing, we handle everything under one roof at our site near St Austell. Whether you’re a project manager looking to hit tight milestones or a contractor seeking consistent supply, our vertically integrated service model ensures reliability from start to finish.
