Marine Steel Grade DH36 Bulb Flats

Posted:1/13/2017 4:42:35 AM

Grades A, AH36 and DH36 bulb flats are primarily used in shipbuilding to reinforce the vessel's hull, in bridge building and for the laying of rail tracks. Marine steel DH36 bulb flats are tailor made for plate stiffening applications. Their special shape provides significant benefits compared with other types of stiffener. Bulb flats provide benefits during the initial steel construction phase, and also during the working life of a ship or other products on which they are used.

Marine Steel Grade DH36 Bulb Flats
Marine steel bulb flats offer many unique benefits for achieving these objectives:
They are “ready to use” plate stiffeners, bulb flats are more cost effective.
The unique shape of a bulb flat distributes steel to maximize resistance to buckling.
The compact shape of a bulb flat offers easy access for welding and painting.
Bulb flats can also reduce coating material while maintaining the same section modulus.
The rounded shape of a bulb flat provides inherent corrosion resistance features. It enhances drainage, and minimise dirt and moisture traps.
The advantages of bulb flats stretch beyond the initial building phase to provide benefits during the working life of a ship. Their shape has inherent corrosion resistance features, and they are more “user friendly” for repair and maintenance, compared with other stiffeners. Recognition of the benefits which bulb flats provide is resulting in increased usage in bridges around the world, both large and small. The advantages that bulb flats offer assist both the initial construction phase as well as the working life of the bridge.
