AL 205 Sliding System Overview

The AL 205 sliding system is designed for aesthetic appeal, durability, functionality, and ease of assembly. Key features include compatibility with double glazing, stainless steel removable rails for enhanced durability and smooth sash movement, two roller size options (22mm and 27mm), structurally stable profiles with versatile corner joints, and a wide range of main and auxiliary profiles. It integrates with the AL 410 opening system for flexible architectural solutions and supports multi-point locking for enhanced security. The system accommodates recessed frame construction in wall gaps up to 60.8mm (glass and mosquito screen) and up to 94.5mm (glass, mosquito screen, and shutter), ideal for renovation and replacement projects.

Advantages of AL 205 System

• Triple rail design supports glass, mosquito screen, and shutter within compact wall openings (up to 94.5mm).
• Combination with AL 410 opening system enables complex constructions such as school buildings with overlapping sashes and dormers.
• Double rail options available for smaller openings (up to 60.8mm).
• Robust stainless steel rails ensure longevity and smooth operation.

Quality Control Methods

• Dimensional tolerance: ±0.40mm for critical nominal dimensions.
• Straightness tolerance: Maximum 3mm deflection over 6m length.
• Warping tolerance: Maximum 2mm deviation at profile ends over 5-6m length.
• Electrostatic paint inspection: No visible surface defects from 2m distance (QUALICOAT recommends 3m).

Profiles and Accessories Catalogue

The catalogue includes a comprehensive range of aluminium profiles and accessories for the AL 205 system, such as single, double, and triple rails (including stainless steel variants), sashes for double/single glass, mosquito screens, shutters, transoms, clip-on hooks, adapters, cover gap profiles, and runners. Each profile is detailed with weight per meter, moment of inertia, moment of resistance, and typical length (6m), facilitating precise structural and design calculations.

Detailed Profile Sections

• Single rail (code 205-111): 507 gr/m, 247 mm perimeter.
• Double stainless steel rail (code 205-122): 844 gr/m, 423 mm perimeter.
• Triple rail for glass, mosquito screen, and shutter (code 205-131): 1157 gr/m, 548 mm perimeter.
• Triple rail for overlapping sashes and mosquito screen (code 205-133): 1238 gr/m, 546 mm perimeter.

These detailed profiles support accurate fabrication and assembly tailored to architectural requirements.

Usage Notes and Limitations

• Certain profiles are not suitable for double overlapping sash constructions.
• Profiles are designed for specific applications including sliding sashes, flush-fitted sashes, mosquito screens, and shutters.
• Additional joint corners enhance assembly flexibility.

Sectional Drawings and Applications

Detailed 1:1 scale sectional views illustrate assembly of various sash types: double and triple overlapping sashes, flush-fitted sashes with shutters or mosquito screens, and single/double flush-fitted sashes. Each section references specific profiles and accessories, providing clear assembly guidance.

Cutting Calculations

Precise cutting formulas and quantities are provided for aluminium profiles used in multiple sash configurations (triple overlapping, quadruple overlapping, flush-fitted single/double sashes). Parameters include height (H), width (L), and derived dimensions (Ha, La, Hc, Lc) with profile-specific constants. The document specifies the number of pieces required per component and glass panel dimensions to ensure accurate fabrication and fitting.

Accessories and Components

The document lists essential accessories such as assembly angles, corner joints, gaskets, rollers, plastic plugs, stoppers, and locking mechanisms. Materials include galvanized steel, stainless steel (INOX), and aluminium. Examples include assembly angles (EA 410-108U), glazing and mosquito screen gaskets (EA 410-422), rollers (ES 210-321), plastic stoppers, and lock kits (ES 210-721).

Manual Punch Machine for Sliding Systems

Details on the manual punch machine (code 26-03-00) used for aluminium sliding systems are provided, including various cutting and perforation tools for water drainage, assembly angles, clip-on hooks, and profile-specific operations. A list of tool codes and descriptions supports precise manufacturing processes.

Construction and Maintenance Instructions

Construction Guidelines

• Manufacturers must be familiar with all profiles and their capabilities.
• Select appropriate construction solutions and pseudo-frames based on window type.
• Maintain a 2.5 to 3 mm clearance between pseudo-frame and frame for easy installation and insulation.
• Cut and bead profiles properly; apply anti-corrosion protection on cut edges.
• Use sealant at profile joints for watertightness and direct water through drainage channels.
• Apply silicone between frame and marble sill to prevent water ingress.
• Create drainage holes at shutter bottoms to avoid corrosion.
• Use only specified accessories and mechanisms from the catalogue.
• EPDM rubber gaskets are recommended for sealing; clip-on types facilitate replacement.
• Glass panes must be properly packed to prevent sagging.
• Seek technical assistance for complex constructions.

Maintenance Guidelines

• Regularly clean painted profiles with water and mild detergent (pH 5-5.8) using a sponge and neutral wetting agent; rinse with clean water.
• Avoid abrasive materials or solvents that damage surfaces.
• Increase cleaning frequency in industrial or coastal areas due to corrosive pollutants.
• Remove construction residues (cement, lime, gypsum) promptly from painted surfaces.
• Avoid direct application of non-approved adhesive tapes on paint.
• Remove factory-applied protective film immediately after installation to prevent sun damage.
• Use special glue on damaged paint areas to maintain gloss and prevent corrosion.
