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.

To support the increase in production and sales of steel gratings, SSG has established its second galvanizing plant adjacent to its steel grating factory. While the first galvanizing plant had been established in 1991 under the name of Siam Steel Galvanizing Co., Ltd. The galvanizing plants not only support the galvanization of gratings for SSG, but also offer galvanizing services for various kinds of steel to our customers.

Therefore SSG is able to offer complete packages in industrial metal flooring installation to its customers, from design and manufacture through final installation and after-sales service. Our technical department is available to assist with any flooring problems and questions a customer may have.

Except Siam Steel Gratings Co., Ltd., there are also Siam Steel Galvanizing Co., Ltd., Rayong Galvanizing Co., Ltd. and Saraburi Galvanizing Co., Ltd., which are offering steel galvanizing services to our customers.

All companies of the SSG group have been certified ISO 9002 in 2000.
