ABOUT US

Siam Steel Gratings Co., Ltd. (SSG) was founded in June 1988 under the name ‘Thai Steel Grating Co., Ltd.’ and began operations in January 1989. In October 1991, Thai Steel Grating Co., Ltd. joined with Progress Manufacturing Pte. Ltd., the largest hot dip galvanizer in Singapore, to form Siam Steel Galvanizing Co., Ltd., which offers galvanizing services to SSG and other customers. In September 1994, Thai Steel Gratings changed its name to “Siam Steel Gratings Co., Ltd.”, under which name it has been well-known until today.

SSG is the largest manufacturer of high-quality steel gratings in Thailand. Our products are used in a multitude of industrial fields. With our new automatic forge-welding machine and newly purchased facilities, SSG is able to produce more than 22,000 sq.m. of steel gratings per month.The company distinguishes itself from
other producers by offering ‘SSG’ gratings, which are manufactured by a special welding machine, created with Austrian technology. Siam Steel Gratings’ products are known for their unique flexibility and control, thanks to the company’s exceptional production process – electro-forged welding. Capable of widening or narrowing bearing bars and cross bars, such a process is electrically and hydraulically powered. The process fuses the metals
together to give maximum resistance from twisting, wearing and distortion. By using this technology,
considerable shaping can be done without destroying or reducing the rigidity and strength of the metal.


Over the years, to support the increase in production and sales of steel gratings, SSG has established its second galvanizing plant adjacent to its steel-grating factory. The first galvanizing plant was established in 1991 under the name Siam Steel Galvanizing. The galvanizing plants not only support the galvanization of gratings for SSG, but also offer galvanizing services for various kinds of steel to customers. In October 1991, Thai Steel Grating Co., Ltd. joined with Progress Manufacturing Pte. Ltd. – the largest hot dip galvanizer in Singapore – to form Siam Steel Galvanizing. Siam Steel Galvanizing Co., Ltd. and Rayong Galvanizing Co., Ltd. support the galvanization of gratings for SSG, and serve a wide variety of other industries in
Thailand as galvanizing specialists.
