Hot Dip Galvanising & Powder Coating

Hot Dip Galvanising & Powder Coating

We're specialists in hot dip galvanising and powder coating - processes that provide the ideal protection for metal in the harshest environments.

BMT has more than 40 years experience in hot dip galvanising techniques, working for multi-national engineering companies, power suppliers, local authorities and independent fabricators.

We have also invested in a sophisticated powder coating plant that can accommodate everything from one-off products to batch runs.

BMT is a one-stop shop for:

  • Hot dip galvanising
  • Hot spin galvanising
  • Zinc phosphate pre-treatment
  • Powder coating
  • Pickling
  • Gritblasting

Galvanising Norfolk

Galvanising Norfolk

We've been providing engineers and fabricators with galvanising services for more than 40 years.

Hot dip galvanizing is a well-established and highly effective steel treatment. Coatings are metallurgically bonded to the base steel, forming an impervious barrier between the substrate and the corrosive environment. Our zinc bath measures 7m x 1.3m x 2.4 mm and is capable of taking items up to three tonnes.

Clean steel components are dipped into molten zinc at a constant temperature and coated with a uniform layer of iron-zinc alloys with pure zinc on the surface. Our process conforms to BS EN ISO 1461:2009, which requires the zinc coating to be an average of 85 microns thick on steel components above 6mm thick.

Hot dip galvanizing holds many advantages over conventional coatings.

Powder Coating

Powder Coating

Our zinc phosphate pre-treatment system and powder coating plant allows us to accommodate items up to 8m x 2.6m. There are eight stages of preparation prior to powder coating, with inspection and temperature testing taking place at each stage.

We can powder coat in any colour on black steel, galvanised and aluminium products, from one-off special items to batches.

Powder coating is applied as a free-flowing, dry powder that, unlike a conventional liquid paint, does not require a solvent.

There are several advantages to using powder coating over conventional liquid paint.

  • It gives off zero or near zero volatile organic compounds (VOC)
  • Can produce thicker coatings without running or sagging
  • Overspray can be recycled to achieve nearly 100% use of the coating
  • It produces less hazardous waste than conventional liquid coatings
  • Items generally have a more consistent appearance
  • A wider range of effects is possible than with other processes.

If you can't deliver your items to us, we'll come and collect them.

Zinc Posphate Pre Treatment

Zinc Posphate Pre Treatment

OUTSTANDING CORROSION RESISTANCE AND LONG LIFE. As soon as the galvanised item leaves the zinc bath the surface reacts with the oxygen in the air to form a thin, impervious film of zinc oxide that has excellent adhesion.

ENHANCED EDGE AND CORNER PROTECTION. Coatings are thicker than plastic-dipped or painted coatings, providing excellent coverage on sharp corners and angles.

HIGHLY ECONOMICAL. Low initial cost combined with long life provides economical protection for long periods - often more than twenty years in hostile environments.

FAST PROCESS. While multi-coat painting can take up to a week, hot dip galvanising can be achieved in just minutes.
