High Quality Hot Dipped Galvanized Press Welded Steel Bar Grating for Walkways/Flooring

Product DefinitionWhat is Steel Bar Grating?Steel bar grating is also known as steel grating. Steel grating is made up of parallel bars that are connected together with perpendicular bars. The bars are most commonly connected through machine pressure welding or manual welding, as the case may be. However, there are other ways of joining the bars together. Alternatives include riveting, close meshing (swaging), and press-locking. The most economical method of joining is determined by the materials used and the bars' thickness.  Steel bar grating is usually made out of carbon steel orstainless steel. It has a very high ratio of strength-to-weight and a lot of open space, making it a widely used option for industrial flooring. However, it is also used for things such as fire escapes, street drains, and bridges.Product FeaturesWhat are the Features of Steel Bar Grating from Tec-Sieve?1. A wide range of material types are available, including carbon steel (cold rolled steel), galvanized steel, and stainless steel.2. 2Nos construct types are available, namely press welded type and press locked type. Note: At Tec-Sieve, in addition to the automatic resistance welding process, the manual welding process is also available, and sometimes the manual welding process will become necessary depending on the individualized specifications of your steel bar grating panels. 3. A wide range of finishes are available, including mill finish (untreated surface in black finish), black, red or any other color primer, and hot dip galvanized finish.4. Two types of top surface are available, namely smooth top surface and serrated top surface.Applicable Quality StandardsSteel Bar Grating StandardsMaterial (Steel) StandardsHot Dip Galvanizing StandardsChinaYB/T4001.1-2019ChinaGB700-88ChinaGB/T13912-2002USAANS/NAAMM(MBG531-88)USAASTM(A36)USAASTM(A123)UKBS4592-1987UKBS4360(43A)UKBS729AustraliaAS1657-1992AustraliaAS3697AustraliaAS1650Technical ParametersAt Tec-Sieve, both press welded steel bar grating panels and press locked steel bar grating panels are manufactured.
