AJR7740 Plaster Profiles: High-Performance Aluminum Corner Protection for Plasterboard and Rendered Walls

When constructing external and internal rendered walls, protecting exterior corners against impact damage and cracking is a critical requirement for long-term structural integrity. Without a specialized corner bead, wall corners are extremely susceptible to chipping, stress cracks from structural movement, and uneven plaster finishes.

Designed and manufactured by JECA DECOR, the AJR7740 Plaster Profile offers contractors, plastering specialists, distributors, and project managers a heavy-duty, highly durable solution for precise corner reinforcement, plaster mud keying, and clean edge alignment.

Product Technical Specifications

Key Features & Practical Performance Benefits

Built with high-grade 6063 aluminum alloy, Model AJR7740 delivers structural rigidity while remaining lightweight for effortless handling on job sites. The corrosion-resistant aluminum substrate ensures the bead will not rust or bleed through rendered wall surfaces over time.

The profile geometry features dual perforated side flanges that allow plaster or rendering mortar to bond firmly through the openings. The central rounded nose acts as a straight screed guide, ensuring perfectly straight, plumb 90-degree corners that withstand impact without cracking.

Whether specified in standard anodized metallic tones or customized powder-coated finishes, our advanced surface treatment processes provide high scratch resistance and seamless compatibility with various wall finishes and fiberglass mesh integration.
