Strength and Durability: GI pipes, especially grade B, have a lower tensile strength compared to materials commonly used in motorcycle frames, such as steel alloys or aluminum. This means they are more prone to bending or breaking under stress, making them unsafe for use in a motorcycle frame that is subject to high forces and vibrations.
Corrosion Resistance: While GI pipes are galvanized to provide some protection against corrosion, the coating can be compromised over time, especially in areas where the pipe is exposed to moisture or salt. This can lead to rust and deterioration of the pipe, weakening its structural integrity.
Weight: GI pipes are relatively heavy compared to other materials used in motorcycle frames. This adds unnecessary weight to the motorcycle, affecting its handling, performance, and fuel efficiency.
Weldability: GI pipes can be challenging to weld effectively due to the presence of zinc coating. Welding galvanized steel can produce harmful fumes and requires special welding techniques, which can increase manufacturing complexity and cost.
Appearance: GI pipes have a dull galvanized finish that may not be aesthetically pleasing for a motorcycle frame.
For these reasons, it is not recommended to use GI pipe grade B in motorcycle frames. Instead, motorcycle manufacturers typically use high-strength steel alloys or aluminum alloys that are specifically designed and tested for the demands of motorcycle construction. These materials offer better strength, durability, corrosion resistance, and overall performance for motorcycle frames.
