LONGFIELD COATING & ENGINEERING PRODUCTS LTD.

A plain, unwound bar gives the lowest coating weight and can be supplied in any diameter and length to suit the application.

Single close coiled wire bars give approximately one tenth the wire diameter in wet thickness. This is the most commonly used bar type.

The Longfield Compound Bar gives a higher coating weight for a given pitch, as well as a greatly improved surface quality.

The Longfield Tri-Compound Bar fulfils the need for heavier coatings but is used increasingly to produce a glossy, line-free finish on medium deposits.

There are many different bar bearings utilising various materials ranging from mild steel (MS) and copper (CU)-based compounds, to polyurethane and PTFE.

Compared with extruded polyurethane, machined polyethylene (PE) bar supports are less impact resistant but are non-absorbent, can withstand higher working temperatures and can last up to three times longer. They are also cheaper to produce and so cost less.

Laboratory-based chemists looking for cost-effective draw-down systems have the choice of three general purpose and one hot-melt machines. Please contact Longfield's Sales Department for current price and availability.

While our suppliers of materials and plating have BS5750 approval, the nature of our products demands standards which are far in advance of those laid down in their approved specification.

As a major supplier of coating bars, Longfield has taken the initiative to provide customers and potential users alike with easy access to a group of independent coating specialists. These are people with considerable expertise in solving some of the most elusive problems. The service each offers is tailored to the specific need.
