Product catalog summary

Steel and Aluminium Load Tables Overview

This document provides specifications and coding conventions for steel and aluminium grating products, focusing on load tables and stock range identification.

Stock Range Coding System

The stock range is encoded using a structured format: [W][30][A][-253]-[PL]-[HDG], where each segment represents a specific attribute of the grating product:

W: Indicates Welded Grating.
30: Load Bar Pitch, measured in millimeters.
A: Cross Bar Pitch, with a standard value of 100mm.
253: Bar Size, specified as 25x3 mm.
PL: Surface type, where 'PL' stands for Plain and 'SR' for Serrated.
HDG: Finish type, indicating Galvanized coating.

Additional Specifications

B=50mm: Cross Bar Pitch alternative dimension.
S: Denotes Swaged Aluminium Grating.

Key Parameters and Definitions

Load Bar Pitch: Distance between load bars, critical for load distribution.
Cross Bar Pitch: Distance between cross bars, affecting structural integrity.
Bar Size: Dimensions of the load bars, influencing strength and weight.
Surface Finish: Plain or serrated surfaces impact slip resistance.
Coating: Galvanized finish provides corrosion resistance.

Summary

This coding and specification system allows for precise identification and selection of steel and aluminium grating products based on structural and surface characteristics. It supports standardized ordering and ensures clarity in product features such as load capacity, dimensions, surface texture, and protective coatings.

Catalog excerpts

Steel Load Table Spans in the darker shading (to the left of the heavy line) have a deflection of less than 5mm for a 4kPa uniformly distributed load. Mass shown is untreated and unbanded. Galvanising and banding will increase the mass as follows; A/B Pattern 12% nominal C/D Pattern 14% nominal F Pattern 16% nominal Load deflection tables are arranged in rising strength order. See the 4kPa, 5mm deflection column. U = Superimposed uniformly distributed load in kPa (100kg/m2 = 0.98kPa) D = deflection in mm for the load U Assumptions for load capacity is on single spans Based on allowable stress...
