There will be no initial shrinkage or swelling of a frame made from TRUECORE steel as there is no absorption or drying of moisture in steel frames. Steel framing in a properly constructed and insulated home expands and contracts in response to temperature changes at rates reasonably similar to those of other building materials. And steel frames won’t shrink, twist or warp over time so there’s less chance of sticking doors and window jambs, nail pops and wavy roof lines due to frame movement.
