Technical Specifications: Roller Shutter Sliding Door Rubber Seal

The RUBASIA roller shutter sliding door rubber seal is a precision-engineered flexible strip manufactured from high-grade EPDM rubber or heavy-duty PVC. It is designed for insertion into the bottom rail of the door leaf, effectively closing the "gap differential" between the door and the floor substrate—typically 3mm to 15mm depending on floor conditions and seal profile selection.

Installation Engineering and Best Practices

Comprehensive Installation Technical Guide

Proper installation is critical for achieving rated performance. RUBASIA provides detailed technical engineering support for all installation scenarios.

Pre-Installation Engineering Assessment

1 Door System Analysis:

◦ Verify door alignment and track condition using laser alignment tools

◦ Measure gap profile at minimum 5 points across door width

◦ Document gap variation (Δgap = max - min) for threshold seal coordination

◦ Assess door operation speed and frequency for seal wear prediction

2 Surface Preparation Engineering:

◦ Clean groove or mounting surface to ISO 8502-3 standard

◦ Remove old seal material and adhesive residue completely

◦ Degrease with isopropyl alcohol (minimum 99% purity)

◦ Ensure surface temperature between +10°C and +40°C for adhesive applications

◦ Verify surface roughness (Rz 20-50μm for optimal adhesion)

3 Material Selection Verification:

◦ Confirm profile matches door groove dimensions (±0.2mm tolerance)

◦ Verify material type matches environmental requirements per selection matrix

◦ Calculate required length: L = door width × 1.02 (2% allowance for compression)

◦ Select appropriate hardness for door weight and closing force

Installation Procedures by Profile Type

Method A: T-Bar Seal Installation (Sliding Fit)

Technical Procedure:

1 Lubrication: Apply silicone-based lubricant (viscosity 100-350 cSt) to groove and seal head

2 Insertion Force: Maximum 50N per meter for manual installation

3 Progression: Work along full length at rate of 0.5m/minute, avoiding stretching (>5% elongation)

4 Trimming: Cut excess length with sharp utility knife at 45° angle, allowing 3-5mm compression at ends

5 End Caps: Install compatible end caps with interference fit (0.2-0.3mm oversize)

6 Verification: Cycle door 5-10 times, measure contact pattern using carbon paper transfer method

7 Acceptance Criteria: Continuous contact line ≥90% of door width

Method B: Wrap-Around Seal Installation

Technical Procedure :

1 Positioning: Raise door to comfortable working height, exposing bottom rail

2 Temperature Conditioning: Allow seal to reach installation temperature (minimum 15°C)

3 Alignment: Position seal centrally on T-bar section with equal overhang both sides

4 Clipping Force: Apply 100-200N linear force to engage retention features

5 Progression: Work from center outward to prevent air entrapment

6 Second Person Assistance: Required for doors exceeding 3 meters width

7 Verification: Check engagement with feeler gauge (maximum 0.5mm gap between seal and T-bar)

Method C: Adhesive-Backed Installation

Technical Procedure:

1 Surface Preparation: Clean with isopropyl alcohol, allow 5-minute flash-off

2 Primer Application: Apply compatible primer if specified, allow 10-minute drying

3 Temperature: Minimum application temperature 15°C, maximum 35°C

4 Pressure Application: Apply 0.2-0.3 N/mm² pressure using roller, 3 passes

5 Curing Time: Minimum 24 hours before door operation

6 Bond Strength Verification: ≥4 N/mm peel strength after curing 

Floor Threshold Seal Integration Engineering

For sites with uneven floors—common in older buildings across towns like Tawau, Sibu, and Kuching—our door seals are designed to work in conjunction with aluminum or rubber floor threshold seals, creating a complete "4-sided seal" solution.
