1. WEATHER-RESISTANT CORTEN STEEL
PRECISION MANUFACTURING
TOPK has secured extremely low bulk pricing. In many cases, we can manufacture steel modular homes at a lower price than standard wood frames. We pass these bulk savings directly to you
DURABLE STEEL STRUCTURES
Steel structures are an excellent choice because they prevent rot, mold, warping, and pest damage that compromise integrity. They easily withstand harsh weather like strong winds and heavy snow!
STEEL PANEL FORMING
When comparing the strength of wood and metal buildings, there is no contest. Steel frames are stronger and lighter. A steel structure is typically 20% to 30% lighter than a similar wooden structure.
