Specifying Wood Floors and Stairs for a Hotel Fit-Out

Hotel wood flooring and staircase specification sourcing in China usually fails at one line in the spec book, and it is rarely the one the buyer is worried about. It is not species, thickness or price. It is the line that reads interior floor finish: Class I per ASTM E648, or Bfl-s1 to EN 13501-1 — a reaction-to-fire requirement that applies because the building is a public one, and that most residential flooring mills anywhere in the world have never had to answer.

This piece is about how to run a hospitality flooring and stair package through a custom mill without getting stopped by that line eight weeks before opening. It covers what one mill can realistically carry across a hotel scope, how the fire question actually works, and what a FF&E consultant will ask for that a residential order never triggers.

What a hospitality flooring package actually contains

A boutique hotel package is not one product. It is four or five products that have to look like one, and they come off different lines with different lead times.

A representative 120-key property:

Against a mill of this type, the published annual figures for Anrantabu Flooring — roughly 200,000 m² of solid relief flooring, 100,000 m² of antique-finish flooring, 500,000 linear metres of skirting and around 1,000 custom staircase sets a year, from a 20,000 m² plant in Huiyang with over 300 handcraft workers — put the whole package at a low single-digit percentage of one year's output. Capacity is not the constraint on a job this size. Sequencing is.

The constraint that matters is that the mill's own stated model is custom, small-to-medium batch project supply rather than commodity volume runs, with production lead confirmed per project schedule rather than published as a standing number. On a hotel programme that cuts both ways: you can get a floor nobody else has, and you cannot assume a fixed week count until the schedule is written into the order.

The grain-match clause has an ordering consequence

The genuinely useful thing a floor-to-trim mill offers a hospitality project is that floors, stairs, skirting and mouldings can be cut from the same timber lot, so grain and colour run consistently from the guestroom plank through the threshold and up the stair.

That is only true if they are ordered together, on one purchase order, against one timber lot. The most common way a hotel package loses its match is entirely commercial: the feature stair gets value-engineered in month two, reinstated in month five, and re-ordered against whatever logs are in the yard by then. Walnut from a different parcel is a different colour. Nobody notices on a sample board; everyone notices where the corridor meets the stair.

Write it as a term. All flooring, stair components, skirting and transition profiles for Phase 1 to be produced from a single timber lot; lot identity to be recorded and stated on the packing list. Then hold the whole package on one PO even if the stair install is nine months out. The same discipline applies to skirting, thresholds and trim grain-matching and to custom stair treads, risers and nosings, which are separate production streams inside the same plant.

The fire question, and why you commission the answer

Here is the honest position, stated plainly because it will save you a month.

Nothing in the published record for this mill — or for most custom parquet workshops selling into residential markets — shows reaction-to-fire test data on its floor coverings. There is no published EN 13501-1 class, no ASTM E648 critical radiant flux figure, no ASTM E662 smoke density result. Treat fire performance as something you commission, own and pay for, not as something you request a copy of.

That is not a defect specific to any one supplier. Reaction-to-fire testing for floor coverings is expensive, build-up specific and commercially pointless for a mill whose customers are private houses. A hotel is the first project in most mills' history that needs it.

What the requirement actually is

Two different systems, and they are not interchangeable.

In the EU and UK, floor coverings are classified under EN 13501-1 with the fl subscript — A1fl, A2fl, Bfl, Cfl, Dfl, Efl, Ffl — plus a smoke sub-class, s1 or s2. The classification comes from EN ISO 9239-1 (the radiant panel test, which produces a critical heat flux in kW/m²) and EN ISO 11925-2 (small-flame ignitability). A wall or ceiling class B is not a floor class Bfl; if a consultant hands you a certificate without the subscript, it is for a different product family.

There is a shortcut worth knowing about. Under the classification-without-further-testing provisions, wood flooring meeting minimum density and thickness conditions and installed in a defined way can be declared at Dfl-s1 without a test being run. That is genuinely useful — and it is also the ceiling. If the spec calls for Bfl-s1 or Cfl-s1, no shortcut exists and a real test on the real build-up is the only route. Separately, wood flooring placed on the EU or UK market falls under the harmonised standard EN 14342, which requires a Declaration of Performance covering reaction to fire, formaldehyde release, slip resistance and thermal conductivity. Settle in writing who issues that DoP — the mill, an importer, or you — before the order, not after.

In the US, the governing test is ASTM E648 / NFPA 253, which measures critical radiant flux: Class I is 0.45 W/cm² or greater, Class II is 0.22 W/cm² or greater. Smoke is measured separately under ASTM E662 / NFPA 258, commonly capped at a specific optical density. Which class applies where — exit enclosures, corridors, guestrooms — comes from the interior finish chapter of the adopted building code and, where the authority having jurisdiction adopts it, NFPA 101. Confirm the adopted code and edition with the AHJ before you write a class into the purchase order, because the answer differs by state and by occupancy.

Three things about fire testing that catch specifiers out

The test is on the assembly, not the timber. The specimen includes the board, the finish, the adhesive and the substrate it is bonded to, tested in the configuration it will be installed in. Change the wax oil, thin the wear layer, switch from full-spread adhesive to a floating install over an acoustic underlay, and the report no longer describes your floor. Lock the build-up before you test, and write the tested build-up into the specification verbatim.

Stairs are usually a different question entirely. A timber tread inside an exit stair enclosure is generally assessed as interior finish or as part of the structure, not as a floor covering, and the requirement is often stricter. Ask your code consultant to rule on the stair separately. While that conversation is open, get slip resistance on the agenda too — a hand-rubbed oil finish on a tread is a reasonable surface, but the DCOF figure under ANSI A326.3, or an R-rating under DIN 51130, is data you should have on the wet-area and stair lines and it does not appear in the published record either.

Somebody has to own the report. Accredited fire testing typically runs to several weeks and a four-figure sum per build-up. Decide up front whether the test is commissioned by you, by the mill at your cost, or by the main contractor, and who is named on the report — because the name on it determines who can use it on the next hotel. If you pay, insist the report is issued in your entity's name and the mill is named as producer.

What to put in the specification pack

A hospitality package needs more written down than a house does, and the mill can only build what you send. The general discipline of writing a product spec sheet for a Chinese factory applies, with hospitality-specific additions:

• Species, cut and grade per scope line, with an agreed grading standard and a physical reference board — "rustic" and "select" mean nothing until two boards are stapled to a wall.
• Moisture content at shipment, set for the destination's conditioned interior. A hotel runs HVAC year-round and typically sits drier than a house in the same city. Specify the target MC and the tolerance band, and require the meter reading on the pre-shipment report.
• Structure per line — solid, three-layer or multi-layer — including wear-layer thickness where engineered, since that determines how many times the floor can be resanded across the property's life.
• Finish system, including number of coats and the maintenance and recoat regime the housekeeping team will actually run.
• Fire class per zone, cross-referenced to the code section, with a note stating the tested build-up.
• Attic stock: 3–5% of every line, same lot, packed and labelled separately, shipped with the main consignment.
• Packing and lot marking, so the site team can lay guestroom floors in lot sequence rather than mixing cartons at random.

One insider point on the oil finish that is worth carrying into the operations conversation. A hand-rubbed wax oil penetrates the grain rather than forming a film on top. In a hotel that is an operational advantage, because a scuffed area can be cleaned, re-oiled and blended in place overnight without sanding and refinishing the whole room — which a filmed lacquer cannot do. It is also an obligation: the property gets a maintenance regime rather than a sealed surface, and if housekeeping treats it like lacquer it will look tired in a year. Get the recoat interval, the specific product and a maintenance kit written into the handover documentation.

Verification before you commit the package

Hospitality buyers get one shot at this; a floor discovered to be wrong at snagging cannot be swapped in six weeks. Before the deposit:

1. Order a full-size sample of each scope line, not a 200 mm chip — a stair tread with the nosing profile, a full parquet panel, a metre of skirting, in the actual species and finish.
2. Ask what hospitality projects the mill has supplied, and whether you may cite or visit them. The mill's own history describes a focus on the domestic high-end residential and hospitality market, and a domestic showroom and dealer network is part of its published profile. Treat that as a starting point for questions, not as a reference: ask for project names, dates, scope and a contact, and verify them yourself.
3. Send the fire requirement in writing before the quote, and ask directly what test data exists today. A supplier who says "none, but we will produce test panels to your build-up" is giving you a workable answer. One who sends a certificate belonging to a different company, a different product or an expired scope is telling you something more important.
4. Book a pre-shipment inspection with moisture readings, dimensional checks and a grade audit against the reference boards. The general approach is covered in pre-shipment inspection for China orders.
5. Fix the schedule in the contract, with the production window, a sample-approval gate and a shipment date. Lead time is confirmed per project rather than published, so it belongs in the order document — the way the weeks distribute is covered in where custom parquet lead times actually go.

Common questions

Can one mill really carry lobby parquet, guestroom plank and the feature stair?

A custom mill running the full chain in-house — timber drying, substrate production, cutting, assembly and finishing — can, and the grain-match across scope lines is the reason to want it. What it cannot do is absorb a scope that arrives in three instalments over a year and still match. The scope has to be complete when the timber lot is selected.

Do I need a separate fire test for each species and finish?

Practically, yes — a reaction-to-fire classification describes a specific build-up. Buyers with several similar lines sometimes test the worst-case configuration (thinnest board, most combustible adhesive, most coats of oil) and argue coverage from there, but that argument has to be accepted by the AHJ or the fire engineer, not assumed.

How does this compare with a domestic contract flooring brand?

A contract brand sells you a floor that already carries a fire class, a wear warranty and local stock, at a price that includes all three. A custom mill sells you a floor nobody else has, without those three, and you assemble them yourself. Neither is wrong; they are different purchases, and the choice hinges on whether the design intent needs something a catalogue cannot supply. The broader hospitality sourcing picture is set out in the hotel FF&E sourcing guide.

What is the single most common failure on these packages?

Ordering the stair and the skirting late. Everything else is recoverable.

What to ask the supplier next

Send these six questions in one message and judge the reply by how specific it is:

1. What reaction-to-fire test data exists today for any product in your range — standard, laboratory, report number, scope and date? If none, will you produce test panels of my exact build-up for a laboratory I appoint, and at what cost?
2. Can floors, stair components, skirting and transitions for my whole scope be produced from a single timber lot, and will lot identity appear on the packing list?
3. What is the production schedule for a package of this size, broken into sample approval, timber selection, machining, assembly, finishing and packing?
4. What moisture content do you ship at, and will the reading appear on the pre-shipment report?
5. What slip-resistance and wear data exists for the oil finish, and what maintenance and recoat regime do you specify for commercial traffic?
6. Which port do you load from, which Incoterms do you offer, and what are your payment terms for a project order?
