Application of SD 46-600 composite metal decking in Shallow-depth floors

The Shallow-depth floors system is more and more widely used, and the selection of the key composite floor is more important, and now we introduce the application of SD 46-600 composite metal decking in the Shallow-depth floors system.

Introduction to the SD 46-600

SD46-600 is the most popular low-rib closed plate type in China, it is mainly used for the steel deck of the thin floor, and has a large later bearing capacity, the bottom surface is flat, the effect is beautiful, and various colors of paint can be painted on the steel plate. The standard profile contains 3 ribs and is 600mm wide with opposing male and female edges, creating an interlocking side lap when installed.

Advantages of the SD 46-600

SD 46-600 is a composite metal decking that can be used as a composite floor slab. due to the unique shape of SD 46-600, the groove ribs can be encapsulated in concrete and used as positive moment reinforcement for the composite floor slab. To a certain extent, it saves the amount of bottom reinforcement and reduces the cost.

With a rib height of only 46 mm, the total floor thickness of SD 46-600 composite metal decking can be as low as 100 mm in the case of thin floor slabs in the Shallow-depth floors system, which is a good news for architects who want to reduce the total thickness of the floor slab.

Based on the unique profile of SD 46-600 composite metal decking, composite floor slabs with SD 46-600 composite metal decking are highly fire-resistant. In case of fire, the groove ribs of SD 46-600 work like the reinforcing steel of ordinary floor concrete. A fire resistance time of 90 minutes can be guaranteed at low slab thicknesses, which is not common in some composite metal decking.

SD 46-600 has a beautiful underside effect that stays flat without a suspended ceiling and can be painted over and used directly as a ceiling.

Due to the above advantages, SD 46-600 is still widely used in shallow-depth floors, and there will be more and more applications in the future.
