How we procure
STEP 1
Specification review
Client spec, utility standard and SLD reviewed; deviations flagged.
STEP 2
Vendor shortlist
OEMs screened for type tests, utility acceptance and lead time.
STEP 3
Technical compliance matrix
Clause-by-clause compliance and declared country of origin.
STEP 4
FAT
Factory acceptance testing with witness and hold points.
STEP 5
Delivery & expediting
Tracked to OTIF; inspection on receipt.
STEP 6
SAT & handover
Site acceptance testing, records and datasheets handed over.
Values are indicative specification ranges, not offers. Gridlinks does not sell online: every supply is engineered against your specification, confirmed in a technical compliance matrix, and subject to current OEM / distributor authorisation.
