windows and interiors.
Our own plant: 22 production lines, three ISO management systems, in-house R&D and quality-control laboratories. We work with distributors and produce under your own brand.

Every figure traces to a datasheet
Most supplier sites give you adjectives. We put the datasheet values on the page — skinning time, service temperature, movement capability, net weight — so you can compare grades before you write to anyone.
Where a grade has no published datasheet yet, the page says so instead of carrying a number we cannot stand behind.
Audited, and made to published standards
Three ISO management systems are certified. Products are made to the Chinese national and industry standards printed on each cartridge — the standard number is on the label, not just on this page.
What to use on site
A task-to-grade matrix. It answers half the questions before the first email.

|---|---|---|
| Window & door installation | BY-808 · BY-101 | PVC, aluminium, timber |
| Facade & rainscreen systems | HP-9900 | stone, concrete, metal |
| Bathroom & kitchen | BY-708 | ceramic, acrylic, glass |
| Interior fit-out | M1 · BY-2000 | plasterboard, timber, MDF |
| Fire-resistant joints | HP-119 | gypsum board, timber, metal |
| Curtain wall & skylights | HP-7000 | glass, stone, aluminium |
From enquiry to quotation in one day
No account, no minimum enquiry, no sales script.
Tell us the joint
Substrate, joint width and depth, expected volume and destination port. A photo of the detail helps more than a long description.
We name the grade
You get one grade recommendation and its datasheet — not a catalogue dump. If nothing in the range fits, we say so.
Price and lead time
A quotation, usually within 24 hours, with carton and container quantities. OEM and private label available on the same lines.
Not a trading company — our own plant
Sealant, foam, fiberglass mesh and facade reinforcement are made on our own lines in Linqu, Weifang. The mesh and the PVC profile in our corner bead are both produced in-house, so the bond and the mesh weight are controlled end to end. Shipping to Europe, South-East Asia and Central Asia.
Tell us the joint, we’ll name the grade
Send the substrate, joint width and volume. You get a grade recommendation, a datasheet and a price — usually within 24 hours.
