Home > Companies > Wincro Metal Industries Ltd > Open Grid Flooring - Stainless Steel

High strength, lightweight, open grid flooring system for use where additional drainage or ventilation is required with high load capacity. It is suitable for use as mezzanine flooring where its open design ensures minimum obstruction of light from one level to another.

The strength of the product is established with the use of computer-controlled production, which ensures that the transverse bars are pressed into the notched load bearing bars under high pressure. Additionally, the large number of connections and an automatically welded frame ensure high strength.

Features and benefits:

  • Cost effective.
  • Can be supplied in easy to handle and economical standard panel sizes or to special requirements.
  • The use of special fittings or brackets with standard nuts and bolts enables the grid to support structures. It can also be welded on site.

Applications:

Regularly used in offshore, chemical and petrochemical industries, dairies, food and bottling plants and in places with extreme heavy traffic load.
