For contractors and specifiers
Tracks, seals, stacking, and the way the wall is used.
This page collects the construction, hardware, installation, and maintenance notes from the July 2024 catalog, rewritten in contractor English. Where the catalog disagrees with itself, both statements are shown.
How the panel is built
Each leaf is a top-hung panel. A trolley runs in an overhead track; the floor has no guide rail. Inside the frame are the sound-insulating core, a drive rod, and the top and bottom retractable seals. The vertical edge uses a magnetic strip and a W-type or M-type anodized-aluminum seal so adjoining leaves pull together and close the joint.
The operating handle works the telescopic seals. Until those seals are retracted, a panel should not be moved, and it should not be stored with the seals still extended — the catalog warns that this can damage the mechanism and scratch the ceiling.
Sealing
The joint is magnetic. The head and sill drop.
The catalog is blunt about a common industry shortcut: relying on sealant tape alone, so a wall looks sealed when it is not. Dayin’s description is that each run of panels includes a telescopic closer, and that a formed rubber section is used at the final joint so the wall is actually closed, not just visually butted.
Edge seals are anodized aluminum in a W-type and M-type double-layer design, intended to close the small gap between panel frames. Top and bottom pressure seals are also anodized aluminum and close the gap to the soffit and the floor.
Track capacity — read both sources
What the catalog says about load
Product pages state a maximum track load per panel. The components table states an ultimate track capacity per metre. They are different units, and on some series the numbers also differ. Confirm the required capacity against panel weight, width, and stacking at quotation stage.
| Series | Product-page load (per panel) | Components table (per metre) | Seal travel, product page |
|---|---|---|---|
| Type 65 | 225 kg | 225 kg/m | 22.5 mm |
| Type 75 | 225 kg | 225 kg/m | 22.5 mm |
| Type 80 | 225 kg (same wording as Type 65/75) | 450 kg/m | 22.5 mm |
| Type 85 | Listed with Type 80 on the same spread | 525 kg/m | 22.5 mm |
| Type 100 | 650 kg; body text also says 22.5 mm seals, table says 30 mm | 750 kg/m | See note |
| Super-high | 3,200 kg; body text 125 mm / 9–17 m | 1,380 kg/m (super-high steel rail) | 30 mm body; 30–50 mm table |

Pass doors
A door in the wall, after the wall is closed
A U-type or L-type door-in-door can be built into a leaf so the room still has an independent entrance once the partition is shut. Single-leaf and double-leaf pass doors are both shown. A wall that includes a pass door has two sets of telescopic seals — one for the leaf itself, and one for the inner door frame. Both must be fully extended before the pass door is used.
Hardware
Tracks, trolleys, junctions, and operating parts
A selection from the accessories spread. Type 50 and glazed-partition parts from that page are omitted, because they are outside this site’s product range.
Materials listed for the components
These are the construction notes from the catalog’s parts page, in brief:
- Track. 6063-T6 anodized aluminum, ceiling-mounted, to carry the hanging panels.
- Double-wheel trolley. POM rollers, 6304-2RS bearings, grade-88 quenched and tempered steel screw (fine thread). The trolley is meant to rotate in the horizontal plane and to pass L, T, and cross intersections.
- Trolley seat. Q235 steel, connecting the trolley to the panel.
- Top and bottom seals. Anodized aluminum.
- Gasket. PVC, tensile strength 8.15 MPa, Shore A hardness 65, tear strength 30 kN/m, black.
- Anodized aluminum. Oxide film 12 μm, tensile strength ≥ 157 MPa, elongation ≥ 8%, other properties to GB/T 5237-1993. The catalog also lists a strength figure of “≥ 58 U M” in the Chinese text; the unit is not expanded there, so we leave it as printed.
- Fibreboard base. PACO medium/high-density fibreboard, density 720 kg/m³, moisture content 6.3%, static bending ≥ 123 MPa, elastic modulus ≥ 2,700 MPa, to GB/T 11718-1999. The catalog prints a formaldehyde figure of 34 mg/100 g and a thickness-swelling figure with a “≥ 15%” sign. Both are unusual as written (a formaldehyde value of 34 mg/100 g would not support an E0/E1 claim for that board, and swelling is normally a maximum). We repeat the figures and do not tidy them away.
- Glass-magnesium board. Sample tested to GB 6566-2001 Class A for radionuclides in finishing materials. Described as suitable as a substrate: anti-slip, nailable, impact- and fire-resistant.
- Acoustic fill. Owens Corning sound-absorbing glass fibre, with fire, thermal, and noise-reduction performance stated as meeting relevant ASTM standards. No specific ASTM numbers are printed.
- Melamine face. 2.44 × 1.22 m boards, described as fire-resistant, smooth, and suitable as a decorative face. Woods listed include walnut, white oak, and sapele, with other colours available.
- Telescopic mechanism and drive rod. Standard 45# steel and spring steel; spring operation is described as adjusting the gap to the floor automatically. The drive rod operates the top, bottom, and lateral seals.
The company culture pages also state that E0/E1-grade materials are specified, and that the factory works to 32 production processes and 108 design details. Those are catalog claims; they sit alongside the component figures above.
Installation, in three phases
- Pre-embed and survey. After the contract is signed, the catalog allows ten working days (adjustable by location) for track pre-embedding, plus a site survey of about seven working days. The visit is used to find the person in charge, check obstacles and slab thickness, write a construction plan, and coordinate with the civil works and with site safety.
- Factory work and delivery. Once the panels are produced, quantities are measured, parts are cut and processed, and the goods are delivered. After the track hangers and decorative connectors are installed, sizes are checked again before handover to the client.
- Installation and commissioning. Track installation is to be levelled — with a water level if the light is too strong for a laser. Column faces are checked for plumb, and turning-position error is corrected. A responsible person is expected on site for acceptance. All sizes are checked at completion.
Operating and looking after the wall
The catalog’s operating notes, rewritten clearly:
- Use the supplied handle (or professional jack) to retract the telescopic seals before you stack or move a panel. This protects the mechanism and the floor.
- Always retract the seals before a panel is parked. Leaving them extended can damage the mechanism and scratch the ceiling.
- On a double-trolley leaf, move the panel with both hands and keep it balanced. A single-trolley track is only to be used where the client or the site conditions require it.
- Bring panels out of the pocket in order. The first leaf is the corrugated / lead panel; the last is the closer.
- A pass-door leaf has two telescopic mechanisms. Both must be fully extended and bearing before the inner door is used.
- Do not swing a hanging panel left and right off the track axis, especially when it is unfastened — the catalog warns this can damage the hanger rod and tear the trolley.
- Do not strike the face with sharp or blunt tools.
- The product is described as having a degree of flame-retardant performance. It is not a place to shelter in a fire.
Maintenance and cleaning
Regular checks: the pass-door lock moves freely; the face is undamaged; gaskets are not split; the telescopic mechanism works; the acoustic seal still does its job; the panel is still firm in its hangers.
Everyday cleaning depends on the face. For a standard vinyl or similar face, the catalog recommends warm water and a mild soap, a clean white cloth, and a dry finish. Oil or grease can be lifted with a household detergent. Paint thinners and other strong solvents are not to be used. Chewing gum or similar residues can be lifted with a pointed wooden tool and then wiped. Anodized aluminum is powder-coated; clean it with a mild soapy water and rinse with clean water so soap does not build up.
