A dent at the gate, a scratch on a panel or a rain streak do not mean the same type of problem. Repairing the cladding of a steel hall must begin with identifying the damage. Painting over the mark may improve the appearance, but it does not always restore the tightness and properties of the element. It is also important to determine the cause so that the same damage does not reappear. A sandwich panel consists of facings and a core that work together to carry loads. Surface damage does not necessarily mean the loss of all properties, but a deep dent requires a broader assessment. In a steel hall, the extent of the damage, its position relative to the supports and the condition of the connections must be checked. The colour of the mark alone does not determine the repair method.

A 100 mm wall panel from a cheaper batch may be used in a new hall if its condition and parameters match the project. The term second grade alone does not explain the reason for the price reduction. The assessment should be based on the specific pieces, the visibility of the walls and the cutting plan. This makes it possible to separate an acceptable cosmetic mark from a defect that matters for the performance of the building envelope. The 100 mm dimension specifies the nominal thickness according to the product designation. On its own it says nothing about the U-value, load-bearing capacity or fire resistance. Data for the specific panel are needed: core, facings, fixing and conditions of use. Panels from different systems do not become interchangeable merely because they have a similar thickness.

Prefabricated components can shorten the route from choosing a solution to delivery on site. For a steel hall to be built efficiently, however, the facility must be ready to receive them. Agreed dimensions, checked site conditions and a defined scope of works are needed. Our standard steel structures can be ordered from available batches. The availability of a specific variant and the collection date are confirmed at the time of order. Our duo-pitch structures cover widths of 8, 10, 12, 14, 16, 18 and 20 m. These are specific series that are worth comparing with the layout of bays or storage areas. A steel hall for warehousing needs space for racking and aisles. In production, access to machinery and the flow of material between process stages are also important.
