Description

Introduction to Aluminium Double Mesh Door:-

An Aluminium Double Mesh Door is a two-panel mosquito screen door system designed to cover wide door openings such as main entrances, balcony doors, and French doors. It consists of two mesh door panels that open from the center or from opposite sides, allowing easy access while protecting indoor spaces from mosquitoes, insects, and dust.

Unlike single mesh doors, the double mesh door is designed for wider door frames, making it ideal for homes with large entrances or high airflow requirements.

The door allows:

• Fresh air circulation

• Natural ventilation

• Outside visibility

• Protection from insects

These doors are commonly used in residential and commercial buildings where large openings require insect protection without blocking airflow.

Basic Structure of an Aluminium Double Mesh Door:-

An aluminium double mesh door is built from several mechanical and structural components working together.

Main components include:

• Aluminium frame structure

• Insect mesh screen panels

• Hinges or sliding tracks

• Locking mechanism

• Magnetic closing system

• Rubber sealing strips

Each part plays a role in durability, functionality, and insect protection.

---

Aluminium Frame Construction:-

The aluminium frame forms the structural backbone of the door.

Most mesh doors use extruded aluminium profiles, which provide high strength with lightweight properties.

Common aluminium grades used:

• Aluminium alloy 6063-T5

• Aluminium alloy 6061

• Powder-coated aluminium profiles

Typical frame specifications:

Many aluminium mesh doors use powder-coated surfaces to prevent corrosion and scratches.

Advantages of aluminium frames:

• Lightweight

• Rust resistant

• Durable

• Easy to fabricate

• Long lifespan

---

Locking and Closing Systems

Double mesh doors use several locking systems to prevent accidental opening.

Common locking types:

• Magnetic closing lock

• Hook lock

• Sliding latch

• Handle lock

Some systems use auto-closing magnets so that the mesh door closes automatically after opening.

---

Sealing Components

To prevent insects entering from the edges, several sealing components are used.

Rubber Gasket

Functions:
