ERW TUBE IDENTIFICATION
Rectangular, Square and Circular Section
Use: Steel Fabricating, Fencing, Furniture, Exhausts
etc.
PHYSICAL DESCRIPTION/PROPERTIES
Appearance: Dull Grey and Silver (Zinc and
Aluminium Coated)
Boiling Point: Not Applicable
Melting Point: Base Metal 1535 Degrees
C
Fire and Explosive Hazard: Steel Products
in the solid state present no fire or
explosive hazard. Under normal fire conditions decomposition
of the metal will not occur, but deformation of
steel member may occur.
HEALTH HAZARD INFORMATION
Steel products under normal conditions do not present
an inhalation, ingestion or contact health hazard.
However, operations such as burning, welding, sawing,
brazing, grinding etc which result in the temperature
of product rising above the melting or surface coating,
may present health hazards.
FUMING
Zinc and Aluminum coated tube is designed so that
weld fume levels are well below the accepted SHORT
TERM EXPOSURE LIMITS (STEL) of 10mg/m2, when normal
welding practices are used.
SPILLS AND DISPOSAL
Recycle scrap steel or dispose at an approved site.
Fire/Explosion Hazard: Irritant fumes may be produced
during a fire situation. Decomposition products
include oxides of carbon.
EFFECTS
OF OVER EXPOSURE
EXPOSURE LIMITS The major exposure hazard
is the inhalation of fumes or dust. Chronic inhalation
of high concentration of iron oxide fumes or dusts
may lead to benign pneumoconiosis (Siderosis). Inhalation
of high concentration of ferric oxide may increase
the risk of lung cancer in persons exposed to pulmonary
carcinogens.
PRECAUTIONS FOR USE
Metal products are stable under normal conditions
of use, storage, handling and transport and require
no special precautions.
When performing normal metalworking operations,
eye and respiratory protection should be used as
necessary.
WELDING
The following consumables are recommended by AS
1544.1-1985 when welding:
Manual metal-arc (MMAW) E41XX, E48XX
Gas metal-arc (MIG) (GMAW) W50x

FIRST AID
Swallowed: Not Applicable
Eye: Holding eyelids open, flood with water
for at least 15 minutes. Seek medical attention
urgently.
Skin: For lacerations, clean and dress wound.
Apply pressure bandage and elevate injured area.
Obtain medical aid urgently. For burns, apply copious
quantities of cool water. Do not apply creams. Seek
medical attention urgently.
Inhaled: Remove from contaminated air. Maintain
breathing with artificial respiration if necessary.
Seek medical attention urgently.
Advice to Doctor: Refer to
section on inhalation hazards for welding operations
involving zinc and aluminium coated steel.
