Staircases, Ladders & Fabrications

Staircases form the primary link between differing levels of floors, platforms and walkways.

It is vitally important that adequate consideration is given to design characteristics such as 'rise' and 'go'. This will be governed by suitability for purpose. anticipated frequency and volume of use. As with platforms, stairs may be fitted with solid or open type treads. Risers may be closed but are more usually open for industrial applications.

Vertical or near vertical fixed access ladders

Vertical or near vertical fixed access ladders should only be installed where occasional access or means of escape is required; and should be provided with safety cages or fall arrest systems where the user could otherwise fall 2m or more, or come into contact with dangerous equipment. Generally ladders should not exceed 6m without an intermediate platform or landing, although there are exceptions to this in certain circumstances.

Companion way, or ships type ladders provide an improved means of access, but generally the vertical rise should not exceed 3.0m.

Where it is necessary for operatives to carry tools or equipment it is always advisable to introduce a staircase for permanent access.

General Fabrications and Architectural Metalwork

Architectural metalwork often places a higher set of demands on designers, manufacturers and installers.

AAI offer a full range of architectural metalwork, using simple concepts and working with a variety of materials, such as stainless steel, brass and coated steels, to achieve a high quality finish

Experienced AAI engineers can advise on all aspects of design and provide recommendations for particular installations.

Dependent upon the nature of the project and the environmental demands being placed upon it, AAI provides all products in a comprehensive range of materials and finishes including:

  • Aluminium Alloy
  • Stainless Steel
  • Mild Steel
  • GRP

All our products are manufactured under the following procedures: ISO 9001: 2015, EN1090-1:2009+A1:2011.
