Metal profile 40x20x2000MM, thickness 1.5mm. Quantity per package: 10 pieces. 4020PSTD

Application and Construction Characteristics

A rectangular steel profile with a cross-section of 40x20 mm and a length of 2 meters is an element that proves effective in construction applications where stiffness is required while maintaining moderate weight. Made from galvanized steel, it does not require additional anti-corrosion treatments under standard indoor conditions, which accelerates the assembly process. A wall thickness of 1.5 mm provides adequate bending strength, allowing for the creation of stable frames, suspended ceiling grids, or lightweight load-bearing structures.

Due to its closed cross-sectional shape, this profile transfers loads more effectively than open angles or channels of similar external dimensions. This is significant when designing structures intended to support heavier finishing or installation elements. The surface galvanization protects against rusting in environments with elevated humidity, although this material is not dedicated to direct contact with water or aggressive chemicals without additional insulation.

Key Features and Technical Advantages

The main advantage of this solution is its versatility in general construction applications and the confirmed quality of materials. The profile possesses ITB technical approval, which is crucial for installers and supervision inspectors – this means the product meets the rigorous requirements of construction standards and can be legally used in facilities requiring formal authorization for use.

It is worth noting several practical aspects resulting from its construction:

• Corrosion protection: The zinc coating acts as a physical and cathodic barrier, extending the service life of the structure even under more demanding storage or operational conditions.
• Ease of processing: Despite the 1.5 mm thickness, this steel remains amenable to cutting with standard tools (angle grinders, metal saws) and bending if adaptation to non-standard shapes is required.
• Dimensional precision: Production ensures a constant 40x20 mm cross-section along the entire 2-meter length, facilitating element joining and achieving straight lines in the finished structure.
• Purchase economy: The profile is sold in bulk packages of 10 pieces, optimizing logistics for larger investments and eliminating the need to order individual elements.

Practical Application

This type of profile finds wide application not only as a load-bearing element but also as a skeleton for various finishing systems. Thanks to its dimensions, it is ideally suited as:

1. Frames for drywall construction (e.g., partition walls, suspended ceilings).
2. Mounting frames for light ventilation or electrical installations (cable trays).
3. Structural reinforcements in metal furniture or industrial shelving.
4. Skeleton elements for temporary fencing or technical enclosures.

During installation, it is important to remember to properly protect cut areas (e.g., with anti-corrosion paint) to avoid local corrosion where the zinc coating has been interrupted by the cutting tool. Thanks to ITB certification and the proven mechanical properties of galvanized steel, this profile constitutes a safe and reliable choice for both construction professionals and individuals undertaking smaller renovation projects independently.
