FAQ
Why do you need to provide on-site drawings and detailed parameters?
In order to better meet your needs, our design team can provide you with grilles that meet your on-site installation needs based on your drawings and parameters, without the need for additional cutting, which will save you some time.
How to calculate the area of each grating?
1. For regular-shaped steel gratings, the area number is equal to the length multiplied by the width, including the cut area of the holes.
2. For special-shaped gratings, the area refers to the area before the steel grating is cut, not the area of the special-shaped grating (which meets the standard requirements).
How is the surface treatment of the steel grating?
The surface treatment methods include hot-dip galvanizing, spraying (color can be customized according to requirements), polishing or no treatment.
What specifications and types of steel gratings do you produce?
Our company can provide customers with any specifications and types of steel gratings. You provide us with your requirements and we ensure that we can meet your needs.
What standards does your steel grating meet?
We are able to produce steel gratings of different national standards, such as China Standard YB/T4001.1-2007, US Standard ANSI/NAAMM (MBG531), British Standard BS4592 and Japanese Standard JJS.
