An 11-gauge is thicker and too heavy for a roof. This coats the whole thing, so it usually takes 20 to 30 years before the steel begins to rust. But when the materials are pre-galvanized, the steel is acquired from the supplier with a zinc coating already on it, then it s cut and welded. Where the steel has been cut, it breaks the rust protection, and rust can occur much sooner. However, Claiser notes that the poly-powder painted coatings can last 15 to 20 years.
Many companies don t have a stamped set of blueprints, and the buyers get stung.
If so, ask these kit buyers what they liked about the package, what they didn t like, and what they might have done differently. During busy times of the year, particularly in late spring and early summer, it might take significantly longer for the company to produce and ship the kit. Absolutely the first step in contemplating the assembly of any structure is a visit or phone call to the local building permit office. It is your responsibility to make sure, prior to purchase, that any package you buy meets those standards and to acquire, if needed, the stamped and sealed blueprints or engineering calculations for the structure that your local building permit office requires. If you order a package that does not meet local building standards, the problem belongs to you, not the manufacturer.
