<p>When a steel structure is erected vertical columns of the structure typically comprise I-sections. In order to provide fire protection for the I-sections and so improve the resistance to fire of the steel structure a column protection system (8) has been developed. The column protection system (8) comprises column protection elements (10a, 10b) which are placed around an I-section (12) the column protection elements (10a, 10b) secure to the I-section (12). Horizontal beams may also be protected by the column protection system.</p> |
