Gauge For Metal Roofing

What gauge is best for metal roofing that will be spanning from purlin to purlin.

Gauge for metal roofing.

Sheet steel is 0188 galvanized is 022 aluminum is 0159 galvanized alloy is 0217 cold rolled is 0179 this being sheet and coil. While there isn t a noticeable difference in appearance between the panel gauges the differing compositions. The appropriate gauge ranges from as light as 26 gauge to as heavy as 20 gauge. They are fire resistant low.

Standard for gauge and decimal equivalents for sheet steel galvanized steel aluminum galvanized alloy coated and of course the cold rolled. Each number represents a range of inches 0 0179 to 0 0217 for example so two roofs may have the same gauge but slightly different thicknesses. Manufacturers express the thickness of metal panels as their gauge with 22 gauge being the thickest and 29 gauge the thinnest of traditionally sold metal roof and wall panels. Metal roofing gauge sizes.

This conversation starts with the gauge you should not use. Metal roof panels are measured by gauge and are usually between 22 and 29. The problem with metal roofing gauge is that there is a wide range of tolerances. Some people may believe that thicker is always better but whether it needs that added strength actually depends on the type of building construction as well as its location.

When it comes to metal roofing gauges thicker typically means that the cost will be higher.

Panels in both size gauges provide the durability benefits of metal. It explains the u s.

So which gauge do you need. Gauge is the thickness of the metal used for a roof. Metal roofing in 29 gauge is just too flimsy to be used in this application. When you choose metal roofing for your project you need to decide which gauge thickness you need from the thinnest 29 gauge to heavy duty 22 gauge.
