Choosing the right coating There are many different coatings to choose from when it comes to coating metal tubular items. The buyer can choose liquid paints, tape- wrap, sacrificial coatings, epoxy coatings or powder coatings.

Delmas is a specialist producer of very small diameter welded precision steel tubes, mainly focused on the 3 to 12mm outside diameter range. The company offers three types of tube that are 100 per cent produced with renewable energy. Premium Delmas tubes are bright and externally precise welded steel tubes. Optim Delmas tubes are tailored tubes to suit the customer’s specific needs – precision calibrated welded steel tubes with bright surface finish, minimised welding bead height, and a guaranteed inner working diameter. Precise Delmas tubes are cold drawn welded precision steel tubes for demanding applications.

thermoplastic powders, with the former product group often referred to as simply powder coatings. Thermoplastic coating powders melt onto the metal under the influence of heat and then solidify into a coating. No reaction takes place and they contain no reactive ingredients. Choosing the most appropriate coating is dependent on the environment the products will be exposed to. If they will be exposed to water, acids in soil, UV light, impacts, abrasion, chemical attack, physical flexing, temperature extremes or graffiti, polyolefin (thermoplastic) coatings can be considered. Thermoplastics are flexible yet tough. They generally cannot chip or crack, and adhere to the metal well. Polyolefin thermoplastics in particular adhere very well to metal without the need for a primer. They contain no plasticisers, BPA or TGIC and nothing can leach into the environment or soil. Polyolefin coatings are typically supplied in powder form and can be easily applied to tubular products

They are of benefit to manufacturers or coaters because primers and chemical curing are not required; they will not chip, crack or flake; and no hazardous fumes are generated on application. The end customer has the reassurance that coated assets will last for decades with little to no maintenance costs, and with no future environmental liability. They are resistant to UV, wind blown sand abrasion and sub zero temperatures, and can withstand the rigours of urban life such as graffiti. Plascoat states that its polyolefin coating powders are becoming increasingly specified in the oil and gas, water and street furniture markets, and are already widely used to coat tubular products in Europe, Asia, Australia, and South and North America.
