Are double wire loops intended for lifting precast units?

No. Wire rope loop boxes are not designed for lifting or dynamic loading. Use dedicated lifting hardware for concrete handling.

How should corner joints be reinforced?

Published guidance recommends a reinforcing bar at the inner edge of the loop fold, with diameter matching the joint reinforcement.

Can loop length and spacing be customized?

Yes. Box length, wire diameter, plate thickness, loop spacing, markings, and packing can follow approved project requirements.

Key features

Double Wire Loop Box provides two flexible wire rope loops inside a steel housing for higher connection capacity across precast wall joints

The double loop format is published for single layer and double layer wall designs where higher load and strength requirements apply

Each loop remains protected in the housing and is released with no-tool tear-off tape before in-situ concrete placement

The connector supports structural joints between adjacent precast elements and between precast concrete and cast in place concrete

Common applications include double sided laminated shear walls solid walls insulated sandwich panels and modular concrete walls

Published construction data includes galvanized steel wire rope up to 1870 MPa plus CE ISO and ISO9001 quality information

Two loops allow coordinated reinforcement engagement across the joint while retaining flexibility for site alignment

OEM production can adapt housing length wire diameter plate thickness loop spacing markings and packaging

Batch inspection standard export packing and coordinated factory supply support repeat precast wall connection programs

Send panel joint geometry and reinforcement details to review the appropriate double wire loop box arrangement

AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier offering 3D software design, ODM, OEM, and multiple customization options. It has five R&D engineers, launched new products during the past year, and provides aluminum die-casting parts. Certifications include ISO9001:2015, ISO45001:2018, ISO14001, and CE. Documented corrective-action and customer-complaint procedures are in place, while quality assurance status and raw-material traceability remain unknown. The supplier reports in-stock capability but lacks overseas warehouses, showrooms, agents or branches, and offline trade-show participation. Its company description states coverage of more than 100 countries and regions, but the overseas-service field separately records zero countries, creating an inconsistency. No financial figures are assessed. Customer evidence includes reported cooperation with many companies globally, but no Fortune 500 cooperation is stated.

Supplier typeThe supplier is explicitly identified as a professional technical supplier and describes itself as serving companies across more than 100 countries and regions. It also states that it can use customer information, samples, and drawings to meet special requirements, supporting its role as a technical and solution-oriented manufacturer.

CertificationsThe supplier holds ISO9001:2015, ISO45001:2018, and ISO14001 management-system certifications, and has CE product-compliance certification. These are explicit certifications supporting quality, occupational safety, environmental management, and product compliance.

After-Sales capabilityThe company description explicitly refers to perfect after-sales service. It also has documented corrective and preventive action and customer-complaint procedures with followed records, although the overall quality-assurance status is unknown.

R&D capabilityThe supplier has five R&D engineers, launched new products during the past year, provides 3D software design, and offers ODM services. However, it explicitly has no available SDK, which limits the evidence for broader technical-integration capability.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, flexible customization, 3D software design, and ODM services. Its request for customer samples and drawings further supports the stated ability to handle customized requirements.

Product Q&A

Q:Why choose a Double Wire Loop Box instead of a single loop unit?

The double loop design is published for higher connection strength requirements and coordinated engagement with joint reinforcement.

Q:Which wall designs can use the double loop box?

It supports single layer and double layer wall designs, including laminated shear walls, solid walls, and sandwich panels.

Q:How are both wire loops released at the joint?

Both flexible loops are secured inside the housing by tear-off tape and can be released without tools before casting.

Q:What reinforcement should connect the two loops?

The joint reinforcement and loop engagement must follow the approved structural design. Published wall guidance references BSt500S bars.

Q:Which wire strength and housing dimensions are published?

Published information includes galvanized wire rope up to 1870 MPa, wire diameters from 6 to 8 millimeters, and plate thickness from 0.5 to 0.7 millimeters.
