Seasoned Teak Wood Door Frames: Technical Specifications, Grading Standards and Fitment Tolerances for Residential and Commercial Projects
At Bhandari Timbers, we understand that selecting the right door frame material is a crucial decision for any construction project. Seasoned teak wood door frames are a preferred choice for residential bungalows, apartment complexes, and commercial spaces due to their natural durability, dimensional stability, and long service life. This guide explores the essential technical specifications, teak wood grading standards, and door frame installation tolerances that architects, procurement managers, builders, and site engineers should consider when choosing teak wood door frames for reliable, long-lasting construction.

Why Seasoning Matters Before Everything Else
Raw or green teak contains significant residual moisture. When this moisture escapes after installation, the timber shrinks unevenly, causing warping, joint gaps and binding doors. Proper seasoning reduces the moisture content to a stable equilibrium so that the frame performs predictably throughout its service life.
Air-dried seasoning: Timber is stacked with spacers in covered, ventilated yards for an extended period. Suitable for standard residential applications.
Kiln-dried seasoning: Controlled heat and humidity cycles bring moisture content down faster and more uniformly. Preferred for air-conditioned interiors and commercial projects where dimensional precision is critical.
For seasoned teak wood door frames intended for interior installation in climate-controlled environments, a final moisture content of 10–12 percent is the accepted industry target. For exterior or semi-exposed locations, 12–15 percent is acceptable provided appropriate surface treatment is applied.
Core Technical Specifications
Standard Section Sizes
Door frame sections are specified by their finished cross-sectional profile. The table below lists commonly used dimensions for seasoned teak wood door frames in residential and commercial projects.
Application Type | Frame Section (Width × Depth) | Rebate Depth |
Light residential interior | 100 mm × 65 mm | 12 mm |
Standard residential exterior | 125 mm × 75 mm | 15 mm |
Commercial single leaf | 125 mm × 90 mm | 15 mm |
Commercial double leaf / heavy duty | 150 mm × 100 mm | 20 mm |
Grain and Density Requirements
High-quality seasoned teak wood door frames should have a straight to slightly interlocked grain, indicating good timber quality and visual appeal. Mature teak typically has a density of 630-720 kg/m³ at 12% moisture content, although actual values vary by species, origin and growing conditions. Inspecting grain patterns, density and moisture content helps buyers assess the suitability of teak for long-lasting door frames.
Natural Oil Content
Teak's natural oils contribute to its resistance to moisture, fungal growth and insect damage. Proper seasoning is essential to achieve dimensional stability while preserving the wood's natural characteristics. Kiln-drying temperatures and schedules should be selected according to the timber's thickness, initial moisture content and intended application to minimise defects such as warping, splitting and excessive shrinkage.
Teak Wood Grading Standards
Understanding teak wood grading standards helps buyers communicate their quality expectations clearly and reduce the risk of receiving timber that does not meet project requirements.
Grade A - First Quality
Grade A teak typically features straight grain, relatively uniform golden to medium-brown colouring, minimal knots and no significant structural defects. It is well suited to exposed door frames and polished hardwood finishes where appearance and consistency are important.
Grade B - Second Quality
Grade B teak may have minor grain deviations, occasional small knots and slight colour variations, provided these do not compromise structural integrity. It can be suitable for painted finishes or applications where some natural variation is acceptable.
Grade C - Utility Grade
Grade C teak may contain more noticeable grain variation, larger knots and limited surface checks, depending on the supplier's grading criteria. It is generally considered for concealed or covered applications where appearance is less critical, provided the timber meets the project's structural and dimensional requirements.
For residential projects, buyers often prefer Grade A or Grade B teak, depending on the finish and budget. Commercial projects requiring exposed hardwood finishes may benefit from Grade A material for greater visual consistency. As grading terminology can vary between suppliers, always confirm the agreed specifications before placing an order with Bhandari Timbers.
Door Frame Installation Tolerances
Correct door frame installation tolerances are just as important as material quality. Even well-seasoned teak wood door frames may cause operational problems if they are installed out of plumb, out of square or without adequate clearance.
Plumb and Level Tolerances
Vertical members (jambs): Check alignment over the full height of the frame using a suitable level or laser.
Horizontal member (head): Ensure the head is level across the full opening width.
Project requirements: Establish acceptable deviations in the project specifications and verify them during installation.
Squareness
Measure both diagonals across the frame opening to check squareness. A significant difference between the measurements may indicate that the frame is distorted or incorrectly positioned. Acceptable tolerances should be confirmed against the door system and project requirements.
Door-to-Frame Clearance
Head clearance: Allow sufficient space for smooth door operation.
Side clearance: Maintain consistent gaps along both jambs.
Bottom clearance: Account for the finished floor level, flooring material and ventilation requirements where applicable.
Exact clearances depend on the door type, hardware, finish and applicable project specifications, so they should be confirmed before installation.
Fixing and Anchoring
Door frames must be securely fixed to the masonry or structural opening using suitable anchors or holdfasts. Their number, spacing and type should be determined by the frame dimensions, wall construction, door weight and project requirements. Anchor pockets should be properly filled and finished to minimise movement and maintain alignment during curing.
Teak Wood Frame Specifications for Different Project Types
Teak wood frame specifications vary according to the requirements of a high-rise commercial building, apartment complex or individual residence. Factors such as frame dimensions, timber grade, moisture content, surface finish, fixing method and expected usage should be defined before procurement to ensure consistent quality and reliable installation.
Specification Variable | Residential | Commercial |
Minimum grade | Grade B | Grade A |
Target moisture content | 10–15% | 10–12% |
Minimum section depth | 65 mm | 90 mm |
Seasoning method | Air-dried acceptable | Kiln-dried preferred |
Anchors per jamb | 3 minimum | 4 minimum |
Surface treatment | Primer or teak oil | Factory primer coat required |
Sourcing Seasoned Teak Wood Door Frames in the Delhi NCR Region

Checklist Before Accepting a Delivery
Before accepting seasoned teak wood door frames, use this checklist to verify that the delivered material matches the agreed specifications:
Verify moisture content: Use a suitable, calibrated moisture meter and check that readings meet the moisture-content range specified for the project.
Inspect for defects: Check each frame section for significant shakes, end splits, excessive knots and other defects against the agreed grading criteria.
Confirm dimensions: Measure the cross-sections at both ends and the midpoint to check dimensional consistency against the purchase specifications and agreed tolerances.
Examine grain orientation: Look for severe cross-grain or irregular grain patterns that could affect strength, stability or appearance.
Check rebate profiles: Ensure that rebates and machined edges are clean, accurately sized and free from excessive tear-out.
Review delivery documentation: Retain available records covering timber grade, seasoning method, moisture content and specified dimensions.
Selecting seasoned teak wood door frames that meet the agreed grading standards and installation requirements can help reduce fitting issues and support long-term performance. Proper installation, suitable finishing and routine care are also important for extending the service life of the frames.
