A well known brand in the market place Apex Longspan comes in Orange and Light Grey with shelf load of up to 780kg. When building any system you need to ascertain the weight load which is to be supported per bay and per shelf followed by the dimensions suitable for the space required and product being stored. All frames come fully assembled. We advise that all frames should be bolted to the floor. It is possible to build up a run of racking with a starter and extension bays.
