Technical resource

Established in 1967 Wells are one of the oldest and biggest British Independents in the business and offer by far the widest range of standard and tailor-made spiral tubes in Europe. Our fourteen tube manufacturing machines enable us to produce spiral tubing in mild steel, galvanised, aluzinc, aluminium and stainless steel as standard in diameters from 41mm up to 2200mm, and in gauges from 0.4mm up to 2.5mm. This facility is backed up by an integral sheet metal work fabrication unit employing the latest CAD/CAM plasma techniques. We believe this capacity to be unrivalled in Europe, and our speed, quality of manufacture, delivery and reputation are unequalled by anyone.
