- PVC conduit from 10 mm to 40 mm in rigid and cold bending grades
- PPR water supply pipe and PVC-U water supply and drainage pipe

About Working With Shingfong
What is your minimum order quantity?
We quote by container load because that is how PVC profile ships economically. Tell us the sizes and the volume you have in mind and we will tell you what fits into one high cube and what it costs.
How long does production take?
Generally 7 to 15 days after we receive your advance payment. The exact date depends on the items and the quantity; loading one high cube takes 5 to 10 days.
What are your payment terms?
T/T with 30% as deposit and 70% before delivery. We send photos of the finished goods and the packed cartons before you pay the balance.
Can you produce to our samples or drawings?
Yes. We produce from your samples or technical drawings and can discuss building a specific mould for your profile.
Do you charge for samples?
Samples for confirming quality and colour are free of charge; the courier fee is paid by the buyer.
Which certifications do you hold?
RoHS, TUV and SGS. Ask us by email and we will send the current certificate copies for the specific range you are buying.
How do you pack the goods?
Generally in PE bags or carton boxes. Trunking is bundled and wrapped in printed white plastic bags; OEM printing on the bag is available.
