01Systems
Three families.
One supply chain.
From the anchor cast into a panel to the floor a tenant walks on — the parts in between come from one group of factories.
All 14 products
Precast concrete components
Anchors, sockets, couplers and sandwich-wall connectors cast into the panel. The full load path from crane hook to structure, with mill certificates and load test reports per batch.
- Lifting anchor, flat type
- Spherical head anchor
- Lifting socket
- Lifting clutch
Prefabricated decoration
Dry-trade systems for the inside of the building: a self-levelling raised floor with pipe and cable separation, prefabricated wall panels and a stainless waterproof base for bathrooms.
- Dry raised floor system
- Prefabricated acoustic partition
Hardware fastening
Worm-drive and quick-release clamps, special fasteners and turned parts in carbon steel, stainless and zinc-plated grades. Made to drawing, from 500 pieces upward.
- Worm-drive hose clamp
- Quick-release hose clamp

Lifting anchor, flat type
Perforated flat anchor cast into the panel face, fixed to the formwork with nails.
Lifting socket
Threaded socket for bolt-on lifting, with a cross hole for a locking pin.
Lifting clutch
Reusable clutch for lifting loops and anchors; releases under load only by hand.
Wire loop box
Plastic recess box that keeps the loop clean and flush with the concrete face.
Dry raised floor system
Developed in 2018: a dry-laid raised floor on adjustable pedestals, with a service void that stays accessible.
Worm-drive hose clamp
American-type clamp with a 1/2" band and a hardened screw; W1 to W4 grades.
03System
A floor that levels itself, without wet trades.
Developed in 2018, when the technical team moved from hardware into interiors. A pedestal grid carries cement-fibre panels; the void underneath stays open for pipes and cables, and every panel can be lifted again for maintenance.
See the system
20 mm panel, 1 mm barrier
Cement-fibre panel over a damp-proof mat; timber or SPC finish by others.
50–80 mm service void
Adjustable pedestals at 400 mm centres; pipes stay reachable from above.
≈ 25 m² per person per day
No screed, no curing time; walkable as soon as the last panel goes down.

05Why LSW
A factory group,
not a trading desk.
Founded in 2010 by three partners who still run the technical side of the business.
Source factory
Three factory bases in Zhejiang cover machining, welding, galvanising and assembly. No middle trader between the drawing and the pallet.
Engineering review
Anchor positions and load cases are checked against the reinforcement drawing before tooling is cut. Ask for the review sheet with your quote.
Batch traceability
Every lot keeps its steel mill certificate, heat number and load-test report, so a claim can be traced back to the cast.
Export handling
FOB Ningbo, CIF or DDP. Packing is designed for sea freight and mixed containers, with pallets that fit a 40HQ without air.
06Process
From drawing
to container.
Standard parts ship from stock. Custom parts follow the same five steps, with a named engineer on the file.
STEP 01
Drawing review
PDF, STEP or a photo of a sample. We check tolerances and material grade.
24 hSTEP 02
DFM and quote
A costed route: machining, coating, packing. Open questions listed in writing.
48 hSTEP 03
Sample
First article with dimensional report, sent by courier before mass production.
7–10 dSTEP 04
Production
Batch cards on the line, in-process checks every two hours, photos on request.
15–25 dSTEP 05
Inspection and shipping
AQL 1.0 final inspection, packing list and photos before the container is sealed.
3 d07Compliance
Paperwork that clears customs and QA.
