Question 1

What materials are Delta drainage products made from?

Accepted Answer

All Delta drainage systems are engineered from prime-quality industrial alloys including Stainless Steel Gr. 304 and 316, chrome-plated cast brass, heavy cast nickel bronze, cast aluminum, and high-tensile cast iron. Each specific alloy is selected with precision based on its intended environmental demands and required load-bearing capabilities.

Question 2

Difference between SS 304 and SS 316?

Accepted Answer

While both grades are high-purity chromium-nickel alloys with exceptional structural durability, Grade 316 stainless steel contains an additional 2% to 3% molybdenum. This specific chemical enhancement significantly upgrades its resistance to chloride-induced pitting and crevice corrosion, making SS316 the standard for marine, pool, or heavy chemical installations, while SS304 is ideal for standard interior restrooms.

Question 3

Are Delta products BS EN 124 compliant?

Accepted Answer

Yes, all heavy duty cast iron grates and gully systems are fully compliant with the international BS EN 124 standard. Our manufacturing processes follow strict safety and loading protocols, certifying and classing our products from light pedestrian Class A15 up to heavy traffic Class D400 loading.

Question 4

Do you provide CAD drawings?

Accepted Answer

Yes, we actively support MEP engineers and architectural specifiers by providing vector CAD blocks in .DWG and .DXF formats, along with robust Autodesk Revit .RFA parametric families. You can download these design sheets instantly via our secure technical resources portal or request them from our support team.

Question 5

Warranty details?

Accepted Answer

All Delta structural drainage products are backed by a comprehensive warranty: 15 years for residential developments and 10 years for commercial installations. This coverage ensures absolute protection against metallurgical corrosion, structural cast failures, and manufacturing defects from the date of handover when installed according to local MEP guidelines.

Question 6

Export availability?

Accepted Answer

Yes, we handle complete global export logistics and shipment dispatching directly from Karachi Port on both FOB and CIF terms. Our export division regularly supplies commercial, healthcare, and industrial scale projects throughout the UAE, Saudi Arabia, Qatar, Oman, East Africa, Central Asia, and the UK.

Question 7

Lead times?

Accepted Answer

For standard catalog items, orders are processed and prepared for container dispatch within 7 to 10 business days of confirmation. Custom alloy castings, bespoke fabricated channel configurations, and non-catalog sizing require a dedicated production lead time of 3 to 4 weeks depending on the sheer scale of the project BOQ.

Question 8

How to select drains?

Accepted Answer

Selecting the optimal drainage system involves calculating several engineering variables, including the target installation layout, chemical exposure risks, required load classes, and the desired aesthetic finish. For instance, high-hygiene food processing plants require marine-grade SS316, whereas light residential bathrooms are best served by polished chrome-plated brass or SS304.

Question 9

Minimum order?

Accepted Answer

There is no minimum order quantity (MOQ) restriction for any standard product listed in our active catalog. However, custom-designed cast products, non-standard bespoke dimensions, and specialized custom alloy runs may require a minimum order volume to offset mold setup and CNC tooling overheads.

Question 10

Custom products?

Accepted Answer

Yes, Delta operates a fully equipped, in-house CNC mold and casting foundry that specializes in bespoke manufacturing. We customize drainage lengths, widths, grating configurations, and specific material grades to meet exact architectural and structural MEP drawings with a standard tooling and production turnaround of 3 to 4 weeks.

Question 11

Maintenance?

Accepted Answer

We recommend performing a simple monthly rinse and wiping for stainless steel gratings with standard non-acidic cleansers to maintain material luster. For cast iron installations in high-traffic commercial environments, a quarterly physical inspection for debris buildup and structural alignment will preserve optimal drainage flow.

Question 12

Bulk order process?

Accepted Answer

To request a commercial quotation, please send your project bill of quantities (BOQ) and structural specifications to our global export division at deltainfofficial@gmail.com, or reach out to us via our official WhatsApp desk. Our sales engineering team will compile and dispatch a comprehensive, formal quotation and compliance matrix to you within 2 to 4 working hours.
