WTC Montreal 2026 is happening right now.
The world’s top tunnel engineers, contractors, and infrastructure specialists are gathered in one place — talking about the future of underground construction.
I’m not there.
I’m here. In my factory in Shandong, China.
Because this is where the fiber actually gets made.
While the conference is running, we’re shipping.
Our macro synthetic fiber has been supplied to tunnel segment projects across China — under China Railway Group, CSCEC, CCCC, and Shanghai Tunnel Engineering.
Not a pilot project. Not a trial batch.
Long-term supply. Repeated orders. Proven performance.
These are some of the most technically demanding tunnel projects in the world — shield tunnel segments, underground metro lines, cross-sea infrastructure.
And they keep coming back to us.
Here’s what our fiber actually delivers in tunnel segment applications:
→ Tensile strength: above 600 MPa
→ Post-crack residual strength f_R3: above 3.0 MPa
→ Energy absorption: above 450 Joules (panel test)
→ Equivalent flexural ratio Re3: above 35%
→ 100% corrosion resistant — no spalling risk over the tunnel’s service life
→ Hydrophilic surface modification — chemical bonding with cement matrix, not just mechanical friction
→ Service life: 50–100 years, matching the concrete structure
This is not standard PP fiber.
Standard PP fiber relies on mechanical anchorage alone. Our modified macro fiber creates both mechanical and chemical bonding with the cement paste — which means stronger pull-out resistance, better crack bridging, and higher residual strength at the same dosage.
The difference shows up in the beam bending test. And it shows up on the job site.
If you are:
→ A tunnel contractor or precast segment manufacturer evaluating fiber suppliers
→ A distributor or importer looking for a verified China manufacturer for your market
→ A concrete materials company sourcing fiber for infrastructure projects
→ An engineer or technical buyer who attended WTC and wants to compare specifications
— then this is exactly the conversation we should be having.
We are not a trading company.
When you contact us, you speak directly with the factory team — the engineers and production managers who have been making this fiber for over 20 years.
We respond to all technical and commercial inquiries within 24 hours.
What we can offer:
✔ Free samples — up to 5 kg, shipped via DHL within 3–5 working days
✔ Full technical data sheet and beam test results
✔ Mix design guidance and dosage calculation for your specific project
✔ OEM and private label — custom length, packaging, and branding
✔ Stable supply — raw material inventory maintained at all times
✔ Global shipping from Qingdao or Tianjin Port
Minimum commercial order: 200 kg
Lead time: 15–20 days after deposit
WTC happens once a year.
The decisions made this week — about which fiber supplier to work with, which specification to adopt, which manufacturer to trust — will shape projects for the next several years.
We may not be in Montreal.
But we have been on the job site.
And we are ready to work with you.
DM me directly on WhatsApp right now.
Tell me your project type and your market.
I will respond personally — with technical data, pricing, and sample arrangements.
No middlemen. No agents. Direct from the factory.
