Tendon Penetration & Structural Failure

Drilling into an unbonded or bonded post-tensioning tendon can cause catastrophic failure — even a single nick reduces tendon capacity by up to 40%. Repair costs often exceed $15,000 per incident.

Core Spalling in Hollow Core Planks

Standard expansion anchors can cause core spalling in hollow core planks, reducing pull-out resistance by 50-70%. This leads to rework, delays, and safety hazards on site.

Unknown Embedment Depth & Pull-Out Risk

Without proper anchoring to hollow core plank engineering data, 30% of field-installed anchors fail pull-out testing (per ACI 355.2). This creates massive liability in overhead or seismic applications.

High Total Cost of Ownership (TCO)

Cheap, non-certified anchors from unknown suppliers lead to 3x more callbacks and 2x longer installation time. Procurement managers report an average 37% cost overrun when using substandard products.

Inconsistent Supply & Long Lead Times

Waiting 8-12 weeks for specialty anchors? Unacceptable for just-in-time projects. Without a reliable supplier, your project schedule — and your reputation — is at risk.

Compliance & Documentation Gaps

Missing ICC-ES, CE, or ISO certs means rejected submittals and delayed payments. Engineers demand traceable, code-compliant products — not generic imports.

Specifically designed for anchoring to hollow core plank applications. Our drop-in anchors feature a controlled expansion sleeve that prevents core spalling and delivers consistent pull-out values. Tested to ACI 355.2 — available in carbon steel, stainless steel, and hot-dip galvanized.

• ✅ Sizes: M6 to M24 (1/4" to 1")
• ✅ Embedment depth: 25 mm – 75 mm
• ✅ Pull-out load: up to 28 kN in C30 concrete

Our anchoring to post tension slab solutions use shallow-embedment, undercut, and adhesive-bonded systems that avoid tendon zones. Each product includes a tendon-safe installation guide and is backed by FEA simulation data. Ideal for 200mm – 300mm thick slabs.

• ✅ Edge distance: as low as 40 mm
• ✅ Seismic tested (categories A–C)
• ✅ Fire rating: up to 120 minutes

From grade 8.8 to 12.9 bolts and galvanized washers, we provide the complete anchoring system. All components are 100% traceable with mill certificates and third-party testing reports. Factory-direct pricing saves you 20-35% vs. distributors.

• ✅ Grades: 8.8, 10.9, 12.9 + stainless steel 304/316
• ✅ Coatings: HDG, Dacromet, Geomet, zinc-nickel
• ✅ Lead time: 15-25 days for standard orders

David M.
Procurement Manager, UK

"We switched to Boen for our anchoring to post tension slab projects. Installation time dropped 22% and zero callbacks. The ICC-ES reports gave our engineer full confidence."

Ana G.
Structural Engineer, Spain

"The drop-in anchors for anchoring to hollow core plank are the best I've tested. Pull-out values exceeded our spec by 18%. Fast shipping and great technical support."

Raj P.
Operations Director, UAE

"Cost savings of 31% compared to our previous European supplier. The galvanized washers and high-strength bolts are consistently high quality. Our new standard for post-tension work."

Q1: What is the best anchor type for anchoring to hollow core plank?

A: For hollow core planks, drop-in anchors with a controlled expansion sleeve are the preferred choice. They prevent core spalling and provide reliable pull-out performance. For heavy loads, adhesive anchors with a mesh sleeve are also recommended. We offer both options with full ACI 355.2 test data.

Q2: How do I avoid damaging tendons when anchoring to post tension slab?

A: Use shallow-embedment undercut anchors or adhesive anchors with a tendon-safe depth mark. Always refer to the post-tensioning shop drawings to locate tendon zones. Our technical team provides a free installation guide with every order, including tendon-safe drilling depths.

Q3: What certifications do your anchors carry?

A: Our anchors are ISO 9001, CE, and ICC-ES certified. We also provide ACI 355.2 compliance reports and ASTM F436 washer certifications. All documents are available for download or can be included with your shipment.

Q4: What is your minimum order quantity (MOQ) and lead time?

A: MOQ for standard anchors is 500 pcs per size. Lead time is 15-25 days for standard orders, and 30-40 days for custom OEM/ODM products. We also offer express shipping for urgent projects — contact us for a quote.

Q5: Do you offer free samples for testing?

A: Yes! We provide free samples for qualified procurement and engineering teams. You just pay the shipping cost. Samples are shipped within 48 hours of request. Request your free sample above.

Q6: Can you customize anchors for my specific project?

A: Absolutely. We offer OEM/ODM customization including material grade, coating, size, and packaging. Our engineering team can work with your specs to create a custom solution. Minimum 1000 pcs for custom orders.

Q7: How do you handle shipping and logistics for international orders?

A: We ship via sea, air, or express (DHL, FedEx, UPS) based on your urgency and budget. We handle all documentation: Bill of Lading, Certificate of Origin, Packing List, and Customs Clearance. We have logistics partners in 30+ countries for smooth delivery.

Q8: What is your payment terms and warranty policy?

A: Payment terms: T/T (30% deposit, 70% before shipment), L/C, or Western Union. We offer a 12-month warranty against manufacturing defects. For bulk orders, we can negotiate extended warranty terms. Full refund if product does not meet spec.
