Gratings are widely used in a number of industrial sectors such as oil and gas production, mining, water and wastewater treatment, power generation, etc. -Rajeev Daswani, Managing Director of Marami Metal Plating speaks on the benefits of hot-dip galvanizing for steel gratings.
According to NACE International - The Corrosion Society, corrosion continues to affect infrastructure worldwide and currently costs an estimated USD 2.2 trillion ever year in degradation and damage to energy production and distribution components, transportation systems, buildings, equipment and much more. However, with the right systems in place, corrosion control technologies could save more than USD 660 billion.
Rajeev Daswani, Managing Director, Marami Metal Plating, said: "A number of studies in the recent years show that almost 25 to 30 percent of the annual corrosion costs could be prevented if companies employ appropriate corrosion management practices."
Gratings can be made of different materials such as carbon steel alloys, aluminum, steel or fiberglass. Each material has its own advantages in terms of usage. For example: Carbon steel industrial flooring gratings are good for high-traffic floor areas; aluminum grating is well suited in situations where strength to weight ratio is important like in wastewater treatment plants; and fiberglass grating is especially good for places where surrounding areas are, or could be, unstable and where additional worker safety is required, as fiberglass grating is electrically and thermally non-conductive.
Steel grating, on the other hand, is the most widely used in situations with elevated temperatures. Steel grating is a kind of open steel member that has its bearing bars and cross bars joining at intersections either by welding or by locking. It is also the staple of the grating industry and many sectors use this type of grating.
However, even though steel is a strong material and is used to provide inherent strengths in industrial projects, it is susceptible to the unseen damaging effects of corrosion. In the long run, unprotected steel can lose structural integrity, giving in to atmospheric attack.
This is where companies like Marami provide the solution of hot-dip steel galvanizing - a method of protecting steel from the damaging effects of the atmosphere by coating it with a a zinc layer.
In this process, coating on the steel or iron is done by passing it through a molten bath of zinc at a temperature of as high as 860 degrees Fahrenheit. No other method of protection matches galvanizing's unique combination of low initial cost, outstanding durability, predictable performance, low to zero maintenance, resistance to atmospheric damage and ease in terms of quality control and inspection. Due to the total immersion process during galvanizing, this process helps coat even the internal parts, recesses and returns of the structure that often do not get coated while using other methods. The coating is subject to damage at a much slower rate of 1/17th and 1/8th that of steel, keeping in mind the environment to which it is exposed.
Marami is one of the few facilities in UAE that has an ISO:9001 and the ISO:40001 certification for their plating services. ISO:9001 is an international standard for the development of quality management systems and ISO:40001 is an international standard for environmental management systems.
Galvanizing is also a very versatile process and items ranging from small fasteners and threaded components, up to major structural members can all be coated using this methods. Other applications of hot-dip galvanizing include beams, bridge structures, fence posts, handrails, ladders, pipes, signal light poles, stair treads, structural steels, towers amongst many others.
Marami Metal Plating is a complete Metal Service Center (MSC) with approximately 18 years of experience in industrial plating and works with highly reputable organizations and multinationals in the construction, petroleum, marine and industrial industries.
