Delivery of long trapezoidal sheets: preparing the site before the truck arrives

Give the narrowest access width, gate clearance and turning space at the entrance. Mark fixed obstacles and overhead lines. The width of the road outside the site alone does not establish access for a vehicle carrying a long load.

Mark the unloading position on the site plan along with excavations, services and site traffic. The ground must suit the equipment and loads proposed. The contractor should check these conditions before confirming the truck booking.

Plan the route after the pack leaves the vehicle too. A tight corner on the way to storage can still prevent sheets from reaching the wall or roof even after a successful unload.

Check piece counts, lengths and roof allocations against the packing list. Mark which pack needs opening first. This reduces rehandling and the risk of scratching coatings while searching for the right length.

If roof and wall colours are similar, identify profile and intended use on the storage plan. Wall sheets may have a different lap edge or coated face. Matching length alone does not make them interchangeable.

Determine the lifting arrangement and support positions for the actual length, weight and packing. Give the crew the manufacturer’s instructions. A T18 or T35 profile designation is not a lifting specification.

Before landing a pack on a roof, confirm the permitted position and load. A concentrated pack acts differently from the distributed weight of the finished covering. Ease of access alone is insufficient for choosing a landing point.

Prepare the supports as specified by the supplier. Keep sheets out of standing water and observe the permitted time in packaging. If a pack arrives wet, establish the correct procedure before putting it into storage.

Compare the work schedule with the protective film removal deadline. Protect coatings when moving sheets and provide a place for cold cutting. Remove cutting swarf from finished sheets.

Before unpacking, check the number of transport units, pack markings and visible corner damage. Photograph tears and bends with the pack number in view. After opening, compare the contents with the piece list.

Give the crew the list of accepted sheets and keep pieces awaiting clarification separate. Resolve any length or profile discrepancy before cutting, while original markings and delivery condition can still be checked.
