B&D Rollmasta Roller Garage Door - Technical Details, Specifications, and Features

Product Overview

Rollmasta is a B&D rolling door model that represents a key product within the B&D garage door range. It is a single continuous curtain rolling door designed to provide security, attractive appearance, and smooth operation when properly installed and maintained according to manufacturer specifications.

Product Classification and Series

Rollmasta is available in multiple series configurations:

• Series 1 Configuration: Model code R1R - A windlocked door product designed for use in Wind Region C, TC2
• Series 3 Configuration: Model code R3F - A door product designed for use in all wind regions with guide support by steel or timber frame

Design and Material Specifications

The Rollmasta door features a continuous steel curtain design with a BLUESCOPE COLORBOND finish incorporating a silicone modified polyester paint formulation. This premium coating provides superior resistance to corrosion and atmospheric effects, making it exceptionally durable in harsh Australian environmental conditions.

The door is engineered as a modular, removable design that can be combined with mullions to accommodate various widths of door openings, offering flexibility in installation across different structural configurations.

• Self-Locking Capability: Automatically locks the door when closed without requiring manual locking

Installation Requirements

Structural Considerations

• Must be mounted behind door openings with specific measurement requirements
• Door guides must be attached to independently designed and certified supporting structures
• Installation in absolutely level position required for proper operation and appearance

Spacing Requirements

• Headroom: Minimum headroom specified based on door model and configuration
• Sideroom: Specific minimum sideroom dimensions required for opener installation
• Backroom: Minimum depth requirements based on door height and curtain sheet configuration
• Garage Depth Requirement: Minimum depths of 2950mm or 3610mm based on door height and configuration

Safety During Installation

• Two-person lift required when mechanical aids unavailable
• Door support must be fitted snugly under door before lifting to prevent crush injuries
• Exclusion zones established around installation area
• Proper pipe wrench techniques required for spring tension adjustments

Maintenance and Care

Regular Maintenance Schedule

• Six-Month Inspection: B&D recommends checking operation at least every six months (more frequently in extreme environments)
• Cleaning: Regular washing with clean water and cloth every 14 days, with special attention to areas not normally washed by rain
• Special Conditions: More frequent washing and additional surface protection recommended for locations with salt air or severe industrial fallout

Component Care

• Nylofelt® Running Strips: Wipe with cloth dampened with mineral turps or methylated spirits; avoid grease or oil which clogs the strips; silicon spray may be used after cleaning
• Door Guides: Regular cleaning and inspection required; must remain straight and perpendicular
• Lock Maintenance: Powdered graphite application if keyway becomes stiff; avoid grease or oil
• Spring Tension: Requires periodic adjustment by experienced door technicians
• Touch-Up Paint: Available from B&D dealers for surface damage repair
