This wood hardness list ranks 75 types of wood by their Janka rating. Explore our wood density chart to see which hardwood is the best for your next project! The Janka hardness scale measures the force that’s required to embed a steel ball halfway through a sample of wood. The ball is 0.444 inches in diameter and fired with increasing force. The pounds of force (or newtons if you’re using the metric system) needed to push the ball to the center is the Janka value you end up with. It’s a great way to measure how resistant a piece of wood is to denting and wear. Our Janka wood hardness chart shows how durable certain wood types are.
We have three options available for your RV cover, including our most popular option, the regular roof cover. This roof cover is ideal for areas where temperate climates and mild weather is the norm. For snowier or more wintry sections of the country, we recommend our other two types of roofs, since they are engineered to withstand more extreme conditions. The boxed eave roof has an A-frame design shelters and is made with stronger material that withstands more brutal weather than the regular roof type shelters. Our vertical roof shelters for our RVs has a vertical design that allows snow to dissipate quickly, which is recommended in areas where harsh weather is common. Work with us to determine which roof type best suits your needs.

We know that RVs come in all shapes and sizes, and that makes it all the more important to choose the right metal RV covers. For RV owners, we are proud to provide a selection of covers and garages in a variety of sizes as well as more than a dozen color choices for the roof and trim. We want you to purchase the RV carport that meets all of your expectations!


All of our cheap steel buildings include free delivery for greater savings, and we’ll also build the structure on your property for free. Your new building will require a level surface for its foundation, though: A level gravel base or a concrete pad is recommended for all buildings we sell at Alan’s Factory Outlet. Placing your modular structure on this type of foundation gives it an extra element of sturdiness. Our prefabricated metal buildings for sale can fit a large number of existing foundations, and if you have any questions about whether your existing site will work for a new metal building, just give us a call and we’ll help you figure out the details.

A motorhome carport can be turned into a garage easily by just adding walls and doors to the structure. Many of our customers who purchase an RV cover online prefer adding side panels to cover one side of the carport for protection from harsh elements. While an awning from the sides doesn’t fully enclose the carport like a metal garage, it does provide the space needed for maneuvering your RV.


“Timing was an extremely important factor for us and we knew no one in America could get a steel building on site quicker than Armstrong Steel - so the choice was easy. With all of the unscrupulous steel building companies out there today, we're glad we chose Armstrong Steel because we got what we paid for and THEN some AND they came through in a pinch!”
