Tecbor\u00ae Boards - Steelwork Protection<\/h1>
<\/div><\/div>[\/vc_column][\/vc_row][vc_row][vc_column width=”2\/3″][vc_column_text css=””]<\/p>\n
Steel structures are used for building purposes worldwide. One of the main advantages is that they have great resistance per weight unit, which provides them with huge versatility and the possibility of creating complex yet light
\nstructures.<\/p>\n
However, the thermal conductivity of steel represents a disadvantage. Therefore, in the event of a fire, the gradual increase in temperature plus steel high heat transmission result in a substantial reduction of the structure\u2019s bearing capacity and mechanical resistance.
\nThe resistance and elastic limit are modified above 250\u00b0C, and above roughly 500\u00b0C the drop in resistance is signifi cant enough not to support its design capacity.<\/p>\n
mcr tecresa\u00ae<\/sup><\/strong>\u00a0has conducted numerous tests with Tecbor\u00ae<\/strong> according to UNE EN 13381-4<\/strong>, standard, in which is determined the contribution of fire protection of the board when we protect steel structural elements, either on
\nbeams, columns or bearing elements.<\/p>\n
Tecbor\u00ae<\/strong> has been tested to cover a great variety of steel profiles characterised by their section factors. Likewise, it has been tested for several standard specifi ed design temperatures.<\/p>\n
