When it comes to construction-related sites, seldom is the case one gets to see innovative design or features, but MetalBuildingDepot.com has managed to escape that rule: this site is a sort of brief encyclopedia of DIY steel building, and home for a manufacturer of steel structures and accessories.
The whole idea is that people get thoroughly informed on how structures work and how they should be built, explore the full catalogue of the company’s products and then proceed to download proprietary design software to make a prototype of the structure they plan to build; after that’s done, they send the file and get an exact quote for their barn, shed, or cover. Does that sound too complex? Don’t worry, they have an instant-quote system which allows users to choose from different kind of buildings, point to specific details (or don’t), and get information from the site directly. While certainly targeted for pros or the advanced DIY crowd, which will definitely be thrilled to hear about this site, I think it would be nice to have some direct eCommerce options, especially when it comes to individual accessories like doors or windows.
