18×20 Garage


30 x 40 garage introduction

Metal garages are structures erected on concrete and using steel as the main construction material. At Steel and Stud, we sell metal carports from galvanized steel, thus assuring you of durability, strength, and style. 

Note, our metal garages are not limited to their design and can be customized to the customer’s needs. What you can change to your interests are; the colors of your door and windows, the size and the number of the windows.

Metal Garage are professionally installed by a team of professionals who have done the work repeatedly, making them experts in the field. Before settling on the design of your 18×20 Garage, we engage with you – the owner – and offer consultation services to determine the exact buildings you desire. 

18×20 Garage

A 18×20 metal garage comes in two styles. The design of choice dictates the cost incurred on the purchase and installation of the buildings.

first style of 30 x 40 garage

A traditional style garage with a straight wall (gable) and a peaked roof is the first style of the 18×20 metal garage. The second one is a dome-shaped carport with vertical walls like the p-shaped one. This is known as a Quonset. The Quonset is more stable and durable compared to the other one. Typically, the dome-shaped carport does not need a complete concrete foundation. This is because its walls can be set to narrow concrete footings. This displays the level of stability of the metal buildings. However, a full slab is recommended in the construction of a garage. 

Prices of 18×20 Garage

A 18×20 garage is ideal for a three or four-car space. Buying and installation of the metal carport will vary depending on several factors. The wall heights, the gauge of the framing and steel sheeting, the number of walk doors and windows, and the choice of having an insulated wall or not. For instance, the cost of a 30x40x12 that has 10×10 doors (roll-up doors) is $24,336. The price is bound to shoot up if you add more doors and windows or if you raise the height of the metal buildings.

Generally, building a metal garage will cost you $11 to $16 per square ft. Compared to a stick or wooden carport which is $35 and $45 per square ft, metal buildings are ideal if you are on a budget.

Uses of a 18×20 Garage

As a store

The uses of a 18×20 garage are very many. The metal buildings can store valuable items such as RVs, cars, boats, and farming equipment, and generally store any items that could need a separate storage facility other than the main house.

Recreational facility

Apart from using the Garage as a storage facility, you could also use it as a recreational facility. Customize the space to a bar with a pool table and other indoor games like darts.

A home office is another idea that the metal garage can be. A home office separate from the noise and interference of the household members could save you a lot of time and resources used in traveling to the office.
