What is the recommended spacing at corner joints when installing steel siding?

The recommended spacing at corner joints when installing steel siding is 1/4 inch. This spacing allows for proper expansion and contraction of the siding due to temperature changes. Steel siding, like many other materials, can expand in warm weather and contract in cooler conditions. A gap of 1/4 inch provides sufficient room for these movements, helping to prevent warping, buckling, or other issues that could arise from not allowing for this natural expansion.

Maintaining this specific gap also supports aesthetic consistency and helps ensure that the siding can be installed smoothly without putting undue stress on the seams or joints. This guideline is important for achieving a long-lasting and visually appealing installation. Proper spacing is a key aspect of siding installation best practices, safeguarding both the functionality and appearance of the siding over time.
