Advantages and material selection of steel gutter

- Oct 16, 2020-

In large-scale factories, steel gutters use a large part of steel, but steel gutters also have their own advantages. The wind load in coastal areas is generally relatively large. If the color plate gutter is used, under the action of strong wind load, the color plate gutter is weak and easy to be lifted by the suction force of the wind, and the design of the steel plate gutter also has a great influence on its durability, so The design and material selection of steel gutter cannot be ignored.

The most commonly used gutter materials are 1.2mm, 2mm, or 2.5mm thick stainless steel; 3mm or 5mm thick galvanized steel; it should be considered based on the importance of the building, the cost, and the grade of other materials used.

The depth of the gutter in general civil buildings should not be less than 250mm. It should be reasonably determined according to the clearance between the bottom of the roof slab and the top of the roof truss, and the space required for the gutter slope adjustment should be considered. When determining the width, consider two factors: First, calculate whether the drainage can pass; second, the commonly used gutter slab width is 1.0m, 1.2m and 1.5m three specifications, try to use the board reasonably, and the building with high requirements must The gutter is designed to be retractable.
