Scope of Security

What is covered

Corrosion Scaling & OxidationMetallurgical oxidation and structural scaling of stainless steel or brass under constant wastewater contact.
Surface Pitting ProtectionChemical pitting on SS316 (CF8M) elements caused by atmospheric salts in coastal projects.
Electroplating DelaminationPremature peeling or flaking of chromium electroplating layer under standard kitchen/bathroom moisture levels.
Asphaltic Coat Bonding FailureLoss of asphaltic dura-coat compound barrier on heavy gray iron grates within the warranty period.
Foundry Manufacturing DefectsPhysical casting bubbles, micro-fractures, or structural dimensional faults discovered within 90 days of procurement.
Exclusion Parameters

What is not covered

Physical Structural AbuseBent grates, fractures, or cracks caused by site installation hammering or driving trucks on pedestrian-rated grates.
Acid Cleaning DamageDirect chemical degradation caused by washing grates with sulfuric, hydrochloric, or highly acidic commercial chemicals.
Gritty Sand AbrasionSurface scratches and wear patterns on mirror-polished chrome coatings caused by abrasive beach sand or building debris.
Neglect of Core MaintenanceFailures occurring due to zero cleaning, causing debris blocks or heavy concrete calcification inside the trap.
Unauthorized Sizing EditsMetallurgical items that are manually cut, welded, or structurally altered from their factory catalog dimensions.
