A gold 3D petal hotel-lobby ceiling is specified as four-petal aluminum squares—typically 1000 × 1000 mm, custom about 300–1200 mm—with interior powder to AAMA 2604 class. Column covers sit in the 1.5–5 mm factory envelope. LINDELACR numbered L-brackets so Thailand Golden Bay’s 1,800 m² canopy and sixteen shafts hang by code.
Hard numbers before adjectives
Hotel lobbies lose money when the metal is specified as “gold feature ceiling.” The useful sheet is module, envelope, coating class, and how the hang is coded. Thailand Golden Bay Resort Hotel is the named check: 1,800 m² of four-petal field, sixteen flared covers, champagne gold, auto-sensing lights in the junctions. The catalog behind that field is LINDELACR’s 3D petal shaped aluminum ceiling panel and the matching metal column cover.

| Interior alloy | Typically 1100 where span and folds are modest |
| Interior coating | Powder, AAMA 2604 class; one gold batch for field + capitals |

| Column plate | 1.5–5 mm |
| Column radius | Min 500 mm / max 5,000 mm |
| Column blank | Max width 1,500 mm; max length 6,000 mm |

Do not copy a tower kPa onto a lobby soffit. Stiffness comes from remaining section, fold, hanger spacing, and how the flare closes on the shaft. LINDELACR sizes those from the scan, then keeps one gauge across the 1,800 m² so a later replacement is the same nest.
How a four-petal module is actually made
The product page calls the unit a concave four-leaf square with a reserved lamp position. In Foshan that is not a printed film. A mill-finish sheet is CNC-formed, the square return is folded, holes are punched in the flange, then the corner is welded and ground so the 3D dish does not oil-can when it hangs. Stacks on the bench show the dish, the flange holes, and a handwritten code on the inner leaf—the same logic used on Golden Bay so a Thai installer is matching numbers, not inventing a hang.
Standard 1000 × 1000 mm is the nest that keeps 1,800 m² affordable. Custom 300–1200 mm exists for a bay that is not a clean multiple, or for a capital ring that must land on a shaft. Rectangular cuts follow the shop drawing. Hidden hanging lugs keep the gold face clean; the L-bracket is the part the crew actually bolts.
Corner brackets (角码) and factory codes
Photos from the Golden Bay run show L-brackets already on the raw petal parts, drilled, with “1” and “2” marked in marker. That is the install spec: weld and grind in Foshan, number to the layout, crate by zone. A cross-border hotel job fails when the first night on scaffold is spent fabricating hangers. LINDELACR’s customized-for-you sequence is scan or survey → CAD → CNC → fold/weld → coat → pack. The 角码 is the last metal step before gold.
The same L-logic runs onto the column skin. An uncoated flare on the green shop floor already carries edge brackets. When the sixteen shafts go together, those brackets are why a seamed wrap can be trial-assembled standing, then packed as coded skins instead of a mystery cone.
Column-cover envelope and the Golden Bay flare
The factory table for aluminum column covers is 1.5–5 mm thickness, radius 500–5,000 mm, width to 1,500 mm, length to 6,000 mm. Square and circular wraps are both in the catalog. Golden Bay is the flared case: a vertical seamed shaft that trumpets into the petal soffit. That radius is not a brochure circle. It is a scan of the lobby, a trial assembly in mill finish, then the same geometry in champagne gold so sixteen capitals match the 1,800 m² field.
Finish options on the product pages include powder, PVDF, and champagne-gold bronze anodizing. For a conditioned lobby, powder to AAMA 2604 class is the default LINDELACR interior language. If a canopy is truly exterior, switch the same geometry to PVDF AAMA 2605 at ≥ 30 μm. Do not mix two golds on one hotel because the sample was anodized and the bulk run was powder.
Lights, glass, and why gold is a batch
Junction fixtures are reserved in the petal CNC. Golden Bay uses auto-sensing lamps that follow outdoor ambient through the courtyard glass. Specify the metal hole and the hang; let the lighting vendor own the driver curve. What LINDELACR owns is one gold across petals, flares, and replacements, and a coded crate so install does not wander a module under the scaffold.
Frequently asked questions
What module size is a 3D petal aluminum ceiling?
The catalog four-petal module is 1000 × 1000 mm. LINDELACR CNC-forms single squares from about 300 mm to 1200 mm, or a rectangle from the shop drawing. Thailand Golden Bay used that modular field across 1,800 m² so replacements stay in the same nest.
What thickness and radius apply to hotel aluminum column covers?
LINDELACR’s metal column-cover envelope is 1.5–5 mm plate, minimum radius 500 mm, maximum radius 5,000 mm, maximum width 1,500 mm, maximum length 6,000 mm. The sixteen Golden Bay shafts sit inside that envelope as flared, seamed wraps—not a catalog kPa.
How are corner brackets and codes used on a petal ceiling?
L-shaped corner brackets (角码) are welded and ground onto the module in Foshan, then hand-numbered. Side flanges already carry drill holes. The site matches code to drawing instead of fabricating hangers on a Thai scaffold.
Is champagne gold on a hotel lobby PVDF or powder?
Interior and sheltered lobbies typically take powder to AAMA 2604 class. PVDF to AAMA 2605 at ≥ 30 μm is the exterior language. Golden Bay’s gold field is an interior architectural coating; LINDELACR locks one batch so sixteen capitals and 1,800 m² of petals do not shift hue.
Send a scan, get a shop file
If the next hotel lobby needs a gold 3D petal ceiling with flared column covers, send LINDELACR the scan or column count. We will return a 1000 mm module note, a coating class, and a Foshan window.
