The construction can carry 75 kg to 90 kg per m2. We advise not to stand directly on the plates. The best way is to put the a shelf with a spool on the construction. You can always release the rubbers and the plating .
When a veranda is 400 cm our more you will need a 3rd pile. If the customer does not like a 3rd pile, it is possible to get a reinforced gutter (at extra cost) or reinforcement beam 15 cm (also at extra cost).
When you have a veranda with roof usually concrete footings are used. One then needs a concrete prepared with drainage, and depending upon the width of the front veranda, one or two standard footings. When you want for example a glass sliding wall, a concrete edge underneath is needed. If you want to place door frames, a founditaion must be provided.
