Quick Answer
Iran project buyers should prepare drawings, a window and door schedule, opening sizes, quantities, product type, glass requirements, hardware requirements, finish preferences, destination details, timeline and documentation needs before requesting a factory quotation. This helps SGL review whether aluminum windows, aluminum doors, glass doors or related systems may fit the project before any quotation is prepared.
Product availability, documentation, payment, logistics, destination requirements and applicable export-control checks must be reviewed before quotation or order acceptance. This checklist is for preliminary project review and quotation preparation only.
Why a Clear Quotation Checklist Matters
Window and door quotations depend on project-specific information. A general request such as "send me aluminum window price" is usually not enough for a reliable review because the factory still needs to know the opening size, quantity, frame system, glass type, hardware, color, destination and project schedule.
For Iran building project inquiries, a clear quotation checklist is especially useful because it helps both the buyer and the supplier confirm product scope before moving into commercial discussion. It also reduces repeated questions, avoids mismatched product assumptions and helps the buyer compare suppliers on the same basis.
SGL Doors & Windows can review buyer-submitted project information for preliminary product and specification discussion. The more complete the information is, the easier it is to identify suitable product directions such as aluminum windows, thermal break aluminum systems, aluminum doors, glass doors or commercial entrance systems.

1. Prepare Project Drawings or Opening Sketches
Project drawings are the most useful starting point for a window and door quotation. They help the factory understand where the products will be installed, how many openings are involved and whether the project needs standard sizes or custom production.
Useful drawing files may include:
- Floor plans.
- Elevations.
- Facade drawings.
- Window and door opening sketches.
- Photos of existing openings for renovation projects.
- Marked-up PDFs showing width, height and opening direction.
If full architectural drawings are not available, buyers can still prepare a simple opening list with width, height, quantity and product type. This is not a final technical drawing, but it can help start a preliminary review.
2. Create a Window and Door Schedule
A window and door schedule is a table that lists each opening in the project. It makes quotation review faster because the supplier can see all units in one place.
| Schedule Field | Example |
|---|---|
| Opening code | W01, W02, D01, GD01 |
| Product type | Aluminum casement window, sliding glass door, entrance door |
| Width x height | 1200 x 1500 mm |
| Quantity | 12 units |
| Location | Floor 2, bedroom, balcony, lobby |
| Opening method | Casement, sliding, fixed, hinged |
| Glass | Double glazed Low-E, laminated, tinted |
| Color | White, black, grey, wood grain or custom |
| Notes | Mosquito screen, privacy glass, special lock, balcony use |
For larger building projects, this schedule helps buyers compare supplier quotations more accurately because each factory is reviewing the same product list.
3. Confirm the Main Product Direction
Before requesting a quotation, buyers should decide which product direction they want to review. If the project is still early, SGL can help compare several options at the inquiry stage.
| Product Direction | When to Consider It |
|---|---|
| Aluminum windows | When the project needs slim profiles, design flexibility, custom sizes or commercial appearance |
| Thermal break aluminum windows | When insulation, comfort and improved frame performance are important |
| Aluminum doors | For entrances, balconies, utility areas and commercial spaces |
| Glass doors | For balcony doors, sliding systems, hinged glass doors and brighter spaces |
| uPVC windows and doors | For buyers comparing budget-sensitive residential options |
| Commercial entrance doors | For higher-use areas where frame strength and hardware selection matter |
The best direction depends on the project drawings, target budget, opening sizes, glass needs, color preference and long-term maintenance expectations.
4. List Glass Requirements Clearly
Glass selection can change the performance, appearance and cost of a window or door package. Buyers should avoid leaving the glass line blank unless they want the factory to suggest options.
Common glass details to prepare:
- Single, double or triple glazing requirements.
- Laminated glass requirements.
- Tempered glass requirements.
- Low-E glass requirements.
- Tinted or reflective glass preferences.
- Acoustic glass needs.
- Privacy glass or frosted glass requirements.
- Glass thickness, if already specified by the project team.
If the project has no final glass specification yet, buyers can describe the application: balcony doors, bedroom windows, commercial facade openings, lobby doors or public-space glazing. SGL can then review possible product directions for discussion.
5. Specify Hardware, Color and Finish
Hardware and finish details are often small items in the early discussion, but they can affect product usability, appearance and quotation accuracy.
Prepare details for:
- Handles and lock style.
- Hinges, rollers, closers and sliding accessories.
- Multi-point locking requirements, if needed.
- Frame color.
- Powder coating, anodized finish or wood grain effect.
- Screen, grille, trim or accessory requirements.
If a project needs a specific color or finish standard, the buyer should provide a sample, color code or reference photo for preliminary review.
6. Clarify Quantity, Destination and Timeline
Quantity affects material review, production planning, packing and quotation structure. Destination and timeline must also be reviewed before quotation planning because each project has different documentation and commercial requirements.
Buyers should prepare:
- Total quantity by product type.
- Approximate total area, if available.
- Project destination or city.
- Target production schedule.
- Target installation or project milestone.
- Required packing or labeling notes.
- Any inspection or documentation requirements.
SGL can review this information at the inquiry stage, but final quotation and order acceptance depend on business review, documentation review and applicable requirements.
7. Share Documentation Requirements Early
Some projects may require technical drawings, product data sheets, packing details, material descriptions or other documents. These requirements should be shared early because they may affect review time and quotation assumptions.
Possible documentation requests include:
- Product drawings or shop drawing support.
- Profile, glass and hardware descriptions.
- Packing list requirements.
- Installation reference information.
- Product photos or sample discussion.
- Certificate or test-document requirements, marked as project-specific and requiring confirmation.
SGL should confirm documentation availability case by case before it is included in any commercial commitment.
8. Ask the Right Questions Before Comparing Suppliers
When comparing window and door suppliers, buyers should look beyond a single unit price. A practical comparison should include product scope, quotation completeness, factory capability, response speed and whether the supplier can review project details clearly.
Useful supplier review questions:
- Can the factory review drawings and a window and door schedule?
- Can it provide aluminum windows, aluminum doors, glass doors and related systems under one project package?
- Can it discuss thermal break systems, Low-E glass, laminated glass and hardware options?
- Can it support custom sizes and project-based production?
- Can it explain what information is missing before quotation?
- Can it clearly separate preliminary review from final commercial confirmation?
These questions help buyers compare suppliers more practically and reduce the risk of unclear quotations.
Common Mistakes That Delay a Window and Door Quotation
| Mistake | Why It Causes Delay | Better Approach |
|---|---|---|
| Asking only for unit price | The supplier cannot know size, glass, hardware or quantity | Send a schedule with dimensions and product type |
| Missing opening direction | Hardware and frame system may be unclear | Mark sliding, casement, fixed, hinged or folding |
| No glass details | Glass has major impact on performance and cost | Provide glass requirements or ask for recommended options |
| No destination information | Commercial and documentation review may be incomplete | Provide destination details for review |
| No timeline | Production and review schedule cannot be assessed | Share target project timeline |
| Comparing suppliers on different assumptions | Quotations become hard to compare | Give each supplier the same drawings and schedule |
