How do I choose between Soaker Hose and Drip Line?

Soaker Hose is cheaper but may over-water at the front. Drip Line has built-in pressure-compensating drippers for uniform distribution up to 100m.

Do I need to install a pressure regulator?

If water pressure exceeds 2.8 bar, add a 1 bar or 1.5 bar pressure regulator to prevent connector failures and uncontrolled flow.

Do I need to dismantle the system for winter?

Above-ground parts: drain water and leave. Timers/filters: remove and store indoors. Underground pipes: use automatic drainage valves.

Do you ship worldwide? What are the shipping costs? How long will it take to receive the products?

We choose the best method based on destination. Delivery time is generally 15-20 days after receiving a 30% deposit.

Do you offer discounts for large orders?

Our products are customizable, and prices are negotiable. Please reach out to our sales team for the best possible price.

What payment methods do you support?

100% TT, or decided after negotiation between both parties.

AI-Powered supplier vetting

SummaryRUNWOO (TIANJIN) NEW MATERIAL TECHNOLOGY CO., LTD is identified as both a trading company and manufacturer/factory in China. It reports ISO 9001 certification, annual galvanized and Aluzinc product capacity of 40,000 tons, design-based customization, ODM and OEM services, and export activity representing 90% of total sales. Quality controls include finished-product inspection instructions, quality assurance, raw-material traceability, and complaint-handling procedures with records. Service strengths include in-stock capability, a stated off-season lead time within 15 workdays, and service quotation/payment terms of FOB/CIF and LC/T/T. Limitations include no overseas warehouse, showroom, agent, or branch, no SDK availability, no offline trade-show participation, and incomplete or unclear evidence regarding financial credibility, customer cases, peak-season lead time, and fire-drill status.

Supplier typeThe supplier is explicitly described as a trading company and manufacturer/factory, while the associated-company industry and company nature are identified as wholesale and retail/trading. This indicates a mixed manufacturing and trading business profile.

CertificationsThe supplier reports holding ISO 9001 certification. The provided information does not specify the certification scope, issuing body, or validity period, but the stated certification is explicit evidence of a quality-management-system certification.

After-Sales capabilityThe supplier has a clear complaint-handling procedure with followed records, in-stock service capability, and an off-season lead time within 15 workdays. However, it lacks overseas warehouses, showrooms, agents, and branches, limiting its directly evidenced overseas service infrastructure.

R&D capabilityThe supplier provides ODM services, customization from designs, and describes continued innovation as a development objective. However, it has no available SDK, and the evidence does not establish a broader R&D system or measurable innovation output.

Production capacityThe supplier reports annual galvanized and Aluzinc product capacity of 40,000 tons, uniformly followed finished-product inspection instructions, quality assurance, and raw-material traceability. These stated manufacturing and quality-control capabilities support a positive production assessment.

Customization capabilityThe supplier explicitly offers ODM services and customization from designs, demonstrating the ability to support customer-specific product or design requirements. No detailed customization scope or limits are provided.

Client casesThe supplier states that it provides OEM services for popular brands, and reports seven years of exporting with exports accounting for 90% of total sales. These statements indicate relevant market experience, but no named customers, projects, or verifiable case details are supplied.

Product Q&A

Q:What thicknesses are available for your drip tape/drip pipes? How long is their lifespan?

Common wall thicknesses are 4mil, 6mil, 8mil, and 15mil. 4-6mil lasts 1 season, 8mil lasts 1-3 seasons, and 15mil is reusable for 3-5 seasons.

Q:What material is your drip tape made of? Is it UV-resistant?

Made from Recyclable polyethylene (PE), HDPE, LDPE, with added UV stabilizers, suitable for outdoor use for 1-2 summers. 100% virgin material products are customizable.

Q:What's the difference between black and red plastic film/drip tape?

Aside from color, some literature suggests that red film can improve yields by 10-20%; both offer similar weed control and insulation effects.

Q:How long is one roll? Can it be cut to my required length?

Regular lengths are 100 ft, 200 ft, and 1,000 ft per roll; some sites offer custom cutting at additional cost, starting from 8 ft.

Q:Should I use adjustable drippers or fixed-flow drippers?

Fixed-flow (pressure-compensating) is for fast installation and same-type plants. Adjustable drippers allow flow from 0-40 L/h for mixed crops.
