6.5 Steelwork
SITEWORK STANDARDS
6.5 - S1 | Sitework standards |
6.5 - S2-S3 | Steelwork |
(a) meet the Technical Requirements
(b) take account of the design
(c) follow established good practice and workmanship
Construction that follows the design and the guidance below will be acceptable for steelwork supporting either masonry partitions or floors.
STEELWORK
Items to be taken into account include:
When materials are delivered to site, check that they conform with either:
- the Engineer's design, or
- the steelwork sizes given in the Appendices to this Chapter.
Bearings for steelwork should be:
- at least 100mm, and
- clean, dry and level.
Padstones may be required in accordance with:
- the Engineer's design, or
- the guidance given in Table 3, Appendix 6.5-A and Table 5, Appendix 6.5-B.
Where steelwork-to-steelwork connections are required, follow either:
- the Engineer's design, or
- the guidance given in Appendix 6.5-C.
Only weld, cut or drill steelwork if it is required by the design.
To ensure durability, steelwork should be given a protective coating system.
For steelwork which is to be bolted (using black bolts), or not connected, an acceptable coating system is one coat of high build zinc phosphate primer and one coat of bituminous paint.
Where steelwork is to be protected by intumescent paint for fire purposes, manufacturers' recommendations should be followed.
STEELWORK - UNGALVANIZED
Internal and external steelwork that has not been galvanized should be protected with at least:
- two coats of zinc phosphate primer, and
- a suitable decorative finish where required.
STEELWORK - GALVANIZED
Unless steelwork is galvanized to a rate of 450g/m2, it should be protected as described for ungalvanized.
