If the two measurements are the same length then it means it's square. Measuring across the diagonal is the best way to check for squareness.

Then the front and back were bolted together, I did this by cutting to length some of the stainless flat stock and clamp them in place to check for squareness and adjusted as needed. The front and back were made first, it was important to make sure to check for squareness as you are building and correct as needed. I wanted the griddle to be portable so it could be tore down for storage and transportation. The frame is made from 1' x 1/8' stainless steel angle and 1' x 1/8' stainless flat stock. The first thing to build was the frame, I sized the griddle to be 22' x 18' so the frame would match those dimensions. This build requires a welder but it is possible to make it with out welding and just bolt all the parts together or using a propane torch to braze certain parts together. The reason for this is stainless steel is a poor conductor of heat and doesn't season well (i.e non-stick). The whole thing will be made from stainless steel except for the griddle cook plate itself, which will be made from mild steel. In this Instructables I'm going to build an outdoor griddle from scratch including the burners.

Another benefit is it keep all the cooking smells and fumes outside. Such as searing steaks, kabobs, fajitas filling and even stir-frys. The big piece of steel is what makes them able to cook lots of food at once and sear foods with ease.Ī grill is great for when you want to cook foods directly over coals or flame but a griddle can cook all those same foods plus more. They basically are a big piece of steel with burners that heat the steel. They are an awesome way to make food when entertaining a group of people. Home griddles are becoming more and more popular.
