Door Manufacturer in China for Global Projects
To request a steel door quotation for a Philippine project, start with three details: dimensions, preferred design and steel thickness. If the specifications are incomplete, the supplier can prepare an initial quotation using clearly stated assumptions and offer alternative configurations. Before confirming the order, the buyer and supplier should resolve the hardware scope, drawing discrepancies and delivery requirements.
In TOF Door’s experience with Philippine enquiries, many conversations begin with a simple message: “We need steel doors” or “We are interested in your steel doors.”
That is enough to start a discussion. The next step is to turn the enquiry into a specification that both sides can understand, price and review.
Dimensions, design and material thickness are TOF Door’s first three specification questions. Buyers should also share the approximate quantity and intended use when available.
These details establish the starting point for a quotation without requiring the customer to have a complete technical package.
| Information | What to send | What needs clarification |
|---|---|---|
| Dimensions | Width and height for each door type | Whether these describe the opening, frame or door leaf |
| Design | A product reference, photograph or drawing | Whether the reference shows the required appearance only or an exact specification |
| Steel thickness | Door-leaf sheet and frame thickness, if known | Whether a stated thickness refers to the steel sheet or the overall door leaf |
| Quantity | Approximate quantities by door type | Whether the quantities are preliminary or confirmed |
| Intended use | Entrance, passage, shaft access or another location | Any special functional or performance requirements |
When steel thickness or other construction details are unknown, buyers can explain the intended application and ask the supplier to propose options.
TOF Door’s approach is to state the assumed configuration in the quotation and, where useful, provide several nearby alternatives. This gives the customer a concrete basis for discussion.
An opening size, an outside-frame size and a door-leaf size are different measurements. A quotation should identify which measurement the buyer has provided.
In TOF Door’s Philippine enquiries, customers generally provide opening dimensions, while some provide door-leaf dimensions. TOF Door therefore reconfirms the measurement basis rather than relying on the numbers alone.
A dimension such as “900 × 2100 mm” is incomplete unless its meaning is stated. Label it clearly on the enquiry or drawing.
For project orders, also provide the wall thickness and available finished-floor information. Installation allowances and frame details should be agreed through drawing review, rather than assumed from an unlabelled size.
An initial quotation can still be useful if its assumptions are visible.
For example, a customer may know the required appearance and opening dimensions but have no preference for the filling material or surface treatment. TOF Door can quote a stated standard configuration and show alternative options for comparison.
The important point is that an assumed specification remains identifiable. It should not become an unnoticed part of the final order.
| Enquiry status | Practical quotation approach | Next action |
|---|---|---|
| Only a general expression of interest | Ask for dimensions, design and steel thickness if known | Establish the basic requirement |
| Dimensions and design available, construction undecided | Quote a stated configuration with relevant alternatives | Compare and select the construction |
| Door schedule available, details inconsistent | Identify discrepancies and record unresolved assumptions | Obtain clarification before final confirmation |
| Configuration and supply scope agreed | Issue a quotation against the agreed information | Review drawings and remaining production details |
This approach helps procurement teams move forward while keeping the basis of the price clear.
A photograph shows appearance, but it does not fully define construction or supply scope.
Two doors may have similar wood-grain finishes or panel designs while using different steel thicknesses, frames, fillings, locks or accessories. One quotation may include hardware that another lists separately.
Before comparing prices, place the specifications side by side.
| Comparison item | What to check |
|---|---|
| Size basis | Are both suppliers pricing the same opening and assembly dimensions? |
| Steel configuration | Are door-leaf sheet thickness and frame thickness stated separately? |
| Door construction | Are overall leaf thickness and filling material identified? |
| Surface finish | Is the same finish requirement being priced? |
| Main hardware | Are the handle, lock, cylinder and hinges included and specified? |
| Special hardware | Are closers or panic exit devices included, optional or excluded? |
| Delivery arrangement | Does the price account for the required delivery phases? |
| Site support | Is any requested measurement or installation guidance included? |
For a wider construction discussion, see Security Doors in the Philippines: How to Choose the Right Construction.
For the standard steel-door configuration described in this guide, TOF Door’s usual hardware package includes:
The quotation should identify the actual hardware supplied for the selected door model.
Door closers and panic exit devices need particular attention. These are special accessories that buyers should request explicitly rather than assume are included.
| Hardware group | TOF Door’s stated usual scope for this configuration | Buyer’s confirmation |
|---|---|---|
| Handle, main lock and cylinder | Included | Confirm selected models |
| Hinges | Included | Confirm the agreed configuration |
| Door viewer | Included | Confirm whether required for each door type |
| Expansion screws | Included | Confirm suitability for the proposed installation |
| Door closer | Special accessory to be specified | Confirm requirement, model and price |
| Panic exit device | Special accessory to be specified | Confirm requirement, model and price |
For doors with specific project performance requirements, agree on the compatible hardware package and supporting documentation for that assembly. A standard hardware list should not be treated as a specification for every application.
A door schedule is a project list identifying door types, quantities and relevant specifications. It is useful for pricing, but it may need to be checked against drawings and other requirements.
TOF Door commonly encounters the following issues during project review:
These discrepancies should be returned to the buyer as clear questions. Choosing one value silently can produce a quotation that appears complete but does not match the intended project.
For each unresolved item, identify the affected door type, the conflicting information and the clarification needed. If an initial price is issued before clarification, state the assumption used.
The total number of doors is only part of the enquiry.
TOF Door also asks about the number of door types, phased deliveries, building and floor allocation, and whether the customer needs site measurement or installation guidance.
These details allow the requested scope to be reviewed alongside production and delivery planning.
| Project detail | Information to provide |
|---|---|
| Door types | Quantity for each design or configuration |
| Delivery phases | Quantities and required timing for each shipment or phase |
| Building allocation | Building identifiers associated with the order |
| Floor allocation | Floor references where project organisation requires them |
| Site measurement | Whether measurement assistance is requested |
| Installation guidance | Whether on-site guidance is requested |
State site-support needs at the enquiry stage. The supplier should confirm availability, scope, timing and any associated charges before the buyer relies on that service.
Some decisions may remain open during initial pricing, but they still need confirmation before production.
In TOF Door’s stated quotation practice, the specific colour choice within the quoted finish options and the opening direction do not change the price. They can therefore be finalised during drawing and production approval.
That does not make them unimportant. An incorrect opening direction can still result in a door that does not suit the intended location.
A request for a different finish system or a revised construction should be reviewed separately rather than treated as a routine colour selection.
When drawings or configurations change, TOF Door prepares a revised quotation and marks the differences. Buyers should review the latest quotation together with the corresponding drawings so that both describe the same order.
Before requesting or approving a quotation, check the following:
| Item | Confirmation needed |
|---|---|
| Project and application | Where each door type will be used |
| Quantity | Total and quantities by door type |
| Dimensions | Measurements with the size basis clearly labelled |
| Wall thickness | Information needed for frame review |
| Design | Selected model, image or drawing reference |
| Steel specification | Door-leaf sheet and frame thickness, or a request for proposed options |
| Construction assumptions | Filling, leaf thickness and finish stated in the quotation |
| Standard hardware | Included components and selected models |
| Special accessories | Closers, panic exit devices and other additions |
| Document discrepancies | Conflicting quantities, dimensions or requirements resolved or identified |
| Delivery plan | Phases, timing, building and floor allocation |
| Site support | Requested services and agreed scope |
| Production details | Colour, opening direction and finished-floor coordination |
| Revisions | Latest quotation and matching drawings |
Yes. Start with dimensions and a preferred design, then provide steel thickness if known. TOF Door can quote a clearly stated configuration and offer alternatives while the remaining requirements are discussed.
Either can be discussed, but label the measurement clearly. TOF Door generally receives opening dimensions from Philippine customers and reconfirms the size basis before proceeding.
TOF Door’s usual package for the standard configuration described here includes a handle, main lock, cylinder, hinges, door viewer and expansion screws. Check the actual quotation for the selected model and application.
Do not assume they are included. State these requirements explicitly and confirm the models and prices in the quotation.
Their construction or supply scope may differ. Compare steel thickness, frame details, filling, finish, hardware and delivery requirements before comparing unit prices.
Under TOF Door’s stated quotation practice, choosing a colour within the quoted finish options or confirming the opening direction does not change the price. Changes to the finish system or construction require a separate review.
TOF Door issues a revised quotation and identifies the differences. Review the updated price and scope against the corresponding drawings before approval.
Yes. Identify these needs early so availability, responsibilities, timing and any charges can be confirmed.
You do not need a fully developed technical package to begin a steel-door enquiry. Send the dimensions, preferred design and steel thickness if available, together with approximate quantities and the intended use.
You can review TOF Door’s steel-door options or send your enquiry and project documents for clarification of the specification and supply scope.
