CONTENTS CEILING SYSTEMS The Hadley Group is one of Europe’s leading manufacturers of cold rolled sections and allied products. Operating from purpose built premises in the heart of the industrial West Midlands in the United Kingdom. The Hadley Group of companies are dedicated to the provision of matchless standards of service, quality, innovation and technical expertise. The integration of advanced research and development with in-house tool manufacture and the construction of its own rolling machines has earned The Hadley Group, its reputation as a major force in cold roll formed...

Ultra 2 The flexibility of the cold rolled forming process has allowed the Hadley Group to adopt a particular design philosophy. This philosophy enhances the flexibility of the process to produce an optimised product. The optimum design for cold rolled steel product can be one that satisfies all the aspirations of both the customer and the manufacturer. These new optimised products are achieved by modifying the shape and/or the surface characteristics of the material incorporated in the profile. The design philosophy has enabled the Hadley Group to obtain the maximum potential from the...

DEFINITION The UltraSTEEL™ process involves working steel in strips with two mating rolls, which produce a dimpled surface and ribbing effect across the surface of the material. During the process, the effective thickness of the material is increased to that of the original thickness plus that of the ribbing. This is achieved by stretching the form into material and not a result of folding in the ribs, which would require extra material. 3 THE THEORY Since the UltraSTEEL™ process involves working steel in strips with two mating rolls, which, produce a dimpled surface and ribbing effect...
