Detailed Product Description
The load bearing bars incorporated in Shangge are produced from steel which conforms to the following equivalent standards: AS3679 Grade 250, BS4360 Grade 43A and ASTM A36.
Shangge is manufactured in numerous combinations of load bar depth and thickness, load bar pitch and cross rod pitch. The full range of standard types of grating are shown on the following pages of this brochure. This range should cover the requirements of any customer; however, if other combinations are required, please contact our sales office. |
| Each Shangge type is coded for easy identification as shown in the following example. |

Series 2-40mm Crs
Series 3-60mm Crs
| In its standard form Shangge is supplied with plain load bearing bars and 6mm square twisted cross rods. |
Serrated
| In its standard form Shangge is supplied with plain load bearing bars and 6mm square twisted cross rods. | Serrated
Serrated grating is available with most standard load bear- ing bars. The serrations are formed by placing a series of notches along the upper edge of the load bar, thus enhanc- ing the non-slip characteristics of the grating. When serrated grating is required it must be nominated (eg. SA325 Series 1 serrated). Use should be made of the serrated conversion factors, shown below the Load Tables, when determining load bearing and spanning capacity.
Design Criteria
The figures shown in the Table of Loads and Deflections have been calculated in accordance with S.A.A. Steel Structures Code - AS3990 for steel having a minimum yield strength of 260 MPA as required by AS3679 Part 1.
Availability
Stock Sheets are manufactured in a standard nominal size 1.0 metre wide x 6.0 metres long, Other widths and lengths are available on request. The most popular grating types can usually be supplied in standard sizes direct from stock.
Our range also includes other combinations of grating.
The delivery time of fabricated panels should be confirmed when an order is placed.
Treatment
Shangge is generally supplied in either of three standard finishes:
1)UNTREATED - no rust protection, thus allowing quicker deliveries to clients who fabricate their own grating.
2)BLACK BITUMEN PAINT - a most economical paint finish where the grating is dipped in a tank of bitumen based paint. There is no pre treatment of the steel before dipping. This coating is most suited for indoor and dry conditions.
3)GALVANIZED - this finish ensures that the entire surface area is protected by a uniform layer of zinc and therefore is suitable for the majority of applications. Hot dip galvanizing conforms to the following equivalent standards: AS1650, BS729 and ASTM A123. The minimum average coating required by these standards is 610gms/sq metre. |
