Galvabond and Galvanneal Steel Material DifferencesBlog | September 13th, 2018
Different types of steel products are needed for varied building and construction or renovation projects today. Many installations on industrial sites also require the use of certain types of steel with specific qualities and levels of strength or endurance. Steel products in rolls or sheets may also be available in different thicknesses and surfaces qualities to comply with regulations for use in different construction or industrial site maintenance. Building planners, architects and building site construction and maintenance experts are all familiar with the qualities, features and functionality levels of these different types of steel.
Major Differences Between Galvabond and Galvanneal Steel
The primary differences between the major qualities and uses of Galvabond and Galvanneal steel today include the following elements and features:
• Galvabond Steel. – Products made of Galvabond steel are manufactured with a continuous hot dip galvanised formation process. They have been pre-designed to meet production specifications such as necessary minimum elongation properties and spangle surface qualities. A wide array of varied surface coating masses and pack sizes are available, according to manufacturing requirements for each product being produced. All Galvabond steel products must meet strict Australian Standards for quality and composition. You can always be assured that BlueScope Galvabond® will meet or surpass all performance expectations and needs.
• Galvanneal Steel. – Both Galvabond and Galvanneal steel are coated with zinc at the steel mills and are manufactured to resist rust and corrosion, and both have been subjected to a hot dip coating process to reinforce rust prevention. Galvanneal steel passes through another annealing process to improve its strength, endurance paint-adhesive surface. For this reason, this type of steel is recommended for a wide variety of projects. Galvanneal steel is ideal for both interior and exterior construction and maintenance projects in industry. After the hot-dip process is completed, diffusion alloying has been induced between the molten zinc coating and the steel, creating a dull matte surface.
Galvanneal steel is conducive to forming into shapes, welding and to accepting and providing a cohesive surface for paint adhesion. For the majority of architectural projects, galvanneal steel is preferred. Galvanneal steel also has a fully spangled finish. Galvanised (Galvabond) steel, however, is less easily formed into shapes, welded or painted.
