Detailed answers addressing engineering considerations, jointing, testing, and consultant submittals.
ALFA manufactured and supplied complete sanitary building drainage systems compliant with DIN 19531 (DN 32mm to 160mm), solvent-weld fittings, and ASTM D1785 Schedule 40 potable water distribution pipes.
DIN 19531 specifies rigid, smooth-bore uPVC formulation with high chemical resistance against domestic detergents and sanitizers, combined with excellent acoustic damping that minimizes drainage noise in active classroom corridors.
We utilize 100% virgin suspension resin stabilized exclusively with organic calcium-zinc compounds. Third-party laboratory extraction tests confirm zero lead, cadmium, or toxic heavy metal leaching.
DIN 19531 pipes are engineered to handle continuous hot waste discharges up to 60°C and intermittent kitchen/laboratory boiling water discharges up to 90°C without softening or joint distortion.
Using ALFA-approved ASTM D2564 heavy-duty solvent cement and ASTM F656 primers, joint fusion creates a continuous monolithic bond that resists thermal cycling and sanitary sewer gas attack.
ALFA provided complete MAR submittal packages including SASO conformity licenses, ISO 9001:2015 registration, hydrostatic proof records, and third-party laboratory chemical resistance reports.
Yes. We fabricated custom puddle-flange wall pass-through pipes ensuring 100% watertight barrier seals against external soil moisture and groundwater ingress through concrete foundations.
Our centralized Jeddah logistics center coordinated phased dispatches to multiple school construction sites simultaneously across Western, Central, and Southern provinces without material delays.
Yes. All supplied DWV materials strictly comply with SBC 701 (Plumbing Code) requirements for building drainage, waste, and vent installations.
Pipes are tested in accordance with ISO 3127 falling weight impact testing at 0°C, ensuring high toughness that prevents breakage during contractor handling and concrete casting.
The mirror-finish interior surface (absolute roughness k ≤ 0.007 mm) prevents the accumulation of grease, scale, and hair, maintaining self-cleansing velocity even under low-gradient installations.
Shipments were backed by manufacturer standard quality warranties and authenticated Mill Test Certificates (EN 10204 Type 3.1) linked directly to each project delivery note.
Yes. Pre-qualified contractor submittal binders are available immediately from our commercial team for rapid incorporation into ministry and institutional bid submissions.
