|Raw Material Verification|
SEM Metalwork considers raw material verification as the most
critical component of quality control. At SEM all raw material are
required to have mill certificates. More importantly primary
components are tested in internationally certified laboratories.
The testing verifies the raw material grade by testing its Chemical
and Physical properties.
Tracking Equipment By Heat
SEM Metalwork closely tracks the raw material throughout the
production process to verify the separation of different heats in
production. Final product is marked with a tracking number
indicating the month and year of production. The tracking number
also verifies the heat number from which the product was made.
In Process Inspection
At SEM Metalwork each production process has its own Quality
control inspector, who is responsible for the quality of
thatdepartment. Each QC is instructed not to pass on quality issues
to the next process. They have the authority not to allow full
production to begin until they have verified the first parts meet
the standard and they have the authority to halt production if a
quality issue appears.
Go/No Go Gauges
Go/No Go gauges are used throughout the production process to
verify consistent quality. They also serve as an inspection tool
that allows for a higher frequency of inspection to be done during
the production. This insures the stability of whole production.
In House Testing Capabilities
SEM Metalwork has well developed capability to perform testing in
house. It allows for critical factors of quality to be tested
consistently. These tests include Flaring and Flattening testing to
verify welding quality, Load Testing to verify material strength,
Salt Spray test and Galvanize thickness Gauges to verify surface
quality, and Fire retardant testing.
Third Party Inspection
In addition to the SEM in process inspection, a Third party
inspection is also offered for the final product. This inspection
team is independent to SEM Metalwork's quality team. They serve as
a second tier of protection to prevent quality issue from leaving
SEM Metalwork performs Quality audits on sub-vendors to verify that
they meet need quality standards. Audits are also performed on
existing vendor to verify that they remain compliant with agreed
Equipment being received from outside vendor is closely inspected.
It can be accepted into production until the Quality Control
department has completely inspection it and approved it.

customer's quality documents are organized on the website and can
