Q1: Why are galvanized hollow sections preferred over painted steel
tubes?
Galvanized tubes provide integrated corrosion protection throughout
the entire surface, while paint coatings can crack, peel, or
require regular maintenance.
Q2: Are galvanized square tubes suitable for coastal projects?
Yes. Hot-dip galvanized square tubes perform exceptionally well in
coastal and marine environments due to their thick zinc coating and
sacrificial protection properties.
Q3: What is the difference between SHS and RHS?
SHS refers to Square Hollow Sections with equal side dimensions,
while RHS refers to Rectangular Hollow Sections with unequal side
dimensions.
Q4: Can galvanized rectangular tubes be fabricated after purchase?
Yes. They can be cut, drilled, bent, welded, and assembled
according to project requirements.
Q5: What zinc coating thickness should I choose?
For indoor projects, lighter coatings may be sufficient. For
outdoor, industrial, or marine environments, a zinc coating of
120–275 g/m² is generally recommended for enhanced durability.
