6.5 - S1
All sitework shall:
(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

6.5 - S2
Steelwork shall be installed to achieve the required structural performance
 

Items to be taken into account include:

(a)
the section size and grade detailed in the design
 

When materials are delivered to site, check that they conform with either:

(b)
bearings
 

Bearings for steelwork should be:

  • at least 100mm, and
  • clean, dry and level.

Padstones may be required in accordance with:

(c)
connections
 

Where steelwork-to-steelwork connections are required, follow either:

Only weld, cut or drill steelwork if it is required by the design.

6.5 - S3
Steelwork shall be protected to achieve the required durability
 

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.
