Gerdau MC12 X 14.3 Channel Stair Stringer Channels

Press release

The MC 12 x 14.3 Stair Stringer Channels are produced at Gerdau’s steel mill in Calvert City, Ky., and are used primarily in the manufacture of stairs frames. The section – introduced by Gerdau to the market in 2003 – is lighter weight and takes less floor space than the C12x20.7 option, while providing flange dimensions often needed in stair framing applications, but not available in the lighter MC12x10.6. The product is less expensive for the customer since it weighs less, and has a slimmer profile that allows for more available space within the stair opening. This profile offers a flange width of 2 1/8”, allowing for a railing post to be fully welded all around and/or the use of a 3/4” rod in the flange. It also has a large section modulus of 12.7” in3, resulting in more versatility in stair width and length and more strength to meet today’s load requirements, compared to the MC12x10.6. The steel is made to conform to ASTM A36 and is also available in other structural grades on an inquiry basis. With the objective of becoming the supplier of choice for customers in the sector, the continued development of the Stair Stringer Channels exemplifies Gerdau’s capacity to send innovative products to the marketplace.
