Powder Coating
Powder Coating is a type of dry coating, which is applied as a free-flowing, dry powder. The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form.
The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a "skin." The powder may be athermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint, and is an ideal finish for costal locations. We offer a large range of powder coat colours.
Advantages of powder coating
1. Powder coatings emit zero or near zero volatile organic compounds (VOC).
2. Powder coatings can produce much thicker coatings than conventional liquid coatings without running or sagging.
3. Powder coated items generally have fewer appearance differences between horizontally coated surfaces and vertically coated surfaces than liquid coated items.
4. A wide range of specialty effects is easily accomplished which would be impossible to achieve with other coating processes.
Galvanised
Galvanising is extensively used for external staircases and offers good paintability and long reliable service life.
The galvanization is made thru the hot-dipping (Hot-dip galvanising) process and gives a very fine greyish matte finish.
The very fine matte finish acts like a primer and easily adheres to paint and it is very rust proof, only white to dark gray marks appear if it comes in contact with water. However it still offers good paintability, weldability, corrosion resistance, and formability.
Hot-dip Galvanised steel has been effectively used for more than 150 years. The value of hot-dip galvanizing stems from the relative corrosion resistance of zinc, which, under most service conditions, is considerably better than iron and steel. In addition to forming a physical barrier against corrosion, zinc, applied as a hot-dip galvanized coating, cathodically protects exposed steel.
Furthermore, galvanizing for protection of iron and steel is favoured because of its low cost, the ease of application, and the extended maintenance-free service that it provides.
