Transportation, Storage and Protection Instructions

Hekim Panel is produced in accordance with TS EN 14509, TSE–ISO 10002 Customer Satisfaction Management System, and the materials are loaded to vehicles with utmost care. After transportation, products must ve carefully unloaded at work site, and panels must be properly protected against rain, mud, etc., environmental conditions until installation.

Important Notice!
Attention must be paid to ensure that all installation surfaces are facing same direction after removing protective film during installation. There might be color shade differences in panels delivered in batches as they belong to different batches. Panels from the same batch should be used or attention should be paid to dates and warning labels.

Transportation

Cranes should be used to unload the materials delivered in stacks on vehicles to to work site, to place them on rooftop or to unload straight from vehicle to rooftop.

In particular, use of suitable cranes for stacks exceeding 8 meters minimize material damage during transportation.

Forklifts equipped with wide forks (~3.5 m) can be used to unload packages with stacking lengths between 6-8 meters, and forklifts equipped with narrow forks (~1.2 m) can be used to unload packages with stacking lengths under 6 meters. If forklifts are to be used for unloading, ensure that the length of stacks extending beyond fork tips is not more than 2.5 meters.

Points of consideration when using crane;
1. Following dimensions and adapter sizes should be observed in order to ensure a balance lifting of the stack using crane. Number of adapter panel connection points should be minimum 3 for panels over 9 m.
2. Nylon, fiber or silk ropes, steel or chain ropes should be employed.
3. In order to prevent damages on material edges that may be caused by ropes, wooden wedges should be placed at the bottom and top of the stack where the ropes contact panels as indicated in the following drawing, and wedges that extend 3-5 cm beyond the stack ends should be preferred.
4. If the materials are to be moved on the roof in stacks, ensure that stack weight is distributed to carrier system equally and stacks are not placed on scissors. It is recommended to adjust inter-stack spaces to ensure minimum horizontal load bearing on the roof in terms of occupational safety and workmanship.

Manual Handling

  • 1. Material should not be grabbed and dragged from one side.
  • 2. Likewise, materials should not be pulled or dragged over horizontal beams once they are placed on the rooftop.
  • 3. Short materials (≤ 4m) should be grabbed from two ends, longer materials should be grabbed from two ends and from center in a balanced manner when lifting them from the stack or transporting them on to rooftop.
  • 4. Do not step on or walk over the bottom material when transporting materials.
  • 5. If there are flaps provided on panels for lengthwise placement on the roof, panel should be lifted from those flaps.

Storage

If the materials will not be installed right away, they should be stacked in a suitable place at work site where they will not required to be moved again. Panel stacking and installation should be carried out using equipment that will prevent damages on the connection edges. Panels that are damaged on connection ends during stacking or installation should not be installed. Otherwise, visual flaws may occur on panel surfaces.
The first choice should be an indoor storage for long term storages. Additionally, materials and storage area should be prevented against air flows. (Temperature difference in stock area should not be more than Δ 10 °C, and relative humidity should not be more than 70%.) The reason for indoor stocking and prevention of air flows is to prevent water introduction and accumulation between two materials. Water or humidity between two panels may lead to paint blisters at material contact points. Such blisters can damage material structure and visual flaws.

If the panels are to be stored outdoors for more than few days, they should be covered under nylon covers in a way to prevent contact with other materials or blocking of air flow.

In particular, painted sheet panels with protective film should be protected against sun light. Thin polyethylene protective film on painted sheets will adhere on panels more strongly if exposed to sun light for extended periods, making them difficult to remove.

Stacking Method

Regardless of storage period length, following aspects and dimensions should be considered when stacking.
  • 1. Do not place more than 3 stacks over each other. Total height should be max. 2.7 cm.
  • 2. Wedges should be placed to give an inclination to the stacks. (~%2-3)
  • 3. Wedge height should be 6-10 cm, and wedge spacing should be maximum 1.5 cm.
  • 4. If there is a wooden pallet underneath the stack, wedges in equal height to the pallet should be placed under stack corners extending beyond the pallet.
  • 5. Wedges between the stacks should be placed in vertical alignment.
  • 6. Styrofoam wedges should be used.
  • 7. Do not step on or walk over the panels.
  • 8. Panels must be placed on level surfaces.
