RE: Safe Working Loads for New Steel Storage Racking,

“Multi Tier Free Standing Outrigger Racking System”

Gamcorp (Melbourne) Pty Ltd, being Structural Engineers within the meaning of Australian

Building Regulations, have carried out a safe working load analysis of the Multi Tier Free

Standing Outrigger Racking System manufactured by Suzhou (China) Sunshine Co., Ltd and

supplied by Associated Projects for use as Steel Storage Racking. The calculations have been

based on the technical information provided by Suzhou (China) Sunshine Co., Ltd and system

configurations through inspection by Gamcorp. Refer to attached Structural Design

Documentation for details.

Safe Working Load per shelf is 150kg. Refer to Safe Working Loads diagram for

details.

This analysis was completed in accordance with Australian Standard AS4048-2012 “Steel

Storage Racking” and with sound, widely accepted engineering principles.

Yours faithfully,

Gamcorp (Melbourne) Pty Ltd
