Yellow Eared Pah Triangle Profile 30x50 mm

Chamfer Triangle Profile with Yellow Lugs 30x50 mm:

Aesthetics and Watertightness in Reinforced Concrete Corners

The Chamfer Triangle Profile with Yellow Lugs 30x50 mm is a technical and aesthetic formwork accessory used in the construction industry for the corner joints of reinforced concrete elements (columns, shear walls, beams, etc.). Its primary purpose is to provide a chamfered (sloped, rounded) finish instead of a sharp 90-degree corner and to increase the watertightness of the formwork system.

The "Yellow" color of this profile is typically a common color used for this type of product in the market, and the "Lugged" design ensures easy installation and a secure grip on the formwork.

Material Properties and Technical Details

The main factor determining the performance of this profile is the material it is made from.

Material Structure: The profile is manufactured from high-durability Rigid PVC (Polyvinyl Chloride) raw material.

Durability: Rigid PVC exhibits high resistance to the aggressive nature of concrete, chemicals, water, and impacts. This feature allows the product to be used multiple times, which provides cost-effectiveness on construction sites.

Dimensions (30x50 mm): This measurement specifies the size of the chamfer that the profile will create. It typically has a triangular cross-section with one right-angle side measuring 30 mm and the other 50 mm. This size is ideal for creating an aesthetic and pronounced chamfer on the corners of reinforced concrete elements of varying thicknesses.

Design (Lugged): "Lugs" or "wings" are located on both sides of the triangular body of the profile. These lugs:

Ease of Fixing: Allows for quick and secure fastening to the formwork panel with nails, screws, or staples.

Watertightness: By closing potential gaps that may occur between the formwork and the concrete pouring surface, it prevents concrete slurry (cement paste) from leaking through these gaps and staining the formwork.

Standard Length: Typically produced in standard rods of 3 meters in length.

Areas of Use and Functions

The Chamfer Triangle Profile performs critical tasks, especially during the formwork stage of reinforced concrete structures:

Creating an Aesthetic Chamfer;

Main Purpose: Softens sharp exterior corners (90°) formed after concrete pouring, providing a smooth, aesthetic, and sloped chamfer finish (typically at a 45° angle).

Why is a Chamfer Desired? Sharp corners can easily break and crack, especially in areas exposed to impact (column edges, building corners). The chamfer minimizes this risk of breakage.

Formwork Watertightness;

Function: Thanks to its lugged structure, when mounted at the joints of formwork panels, it prevents the cement slurry, which is the liquid part of the concrete, from leaking out. This ensures a smoother and more homogeneous appearance on the surface of the reinforced concrete element.

Structural Benefit;

Strength: Rounding (chamfering) the corners can slightly increase structural strength by reducing stress concentration in that area of the concrete.

Sectors Used and Target Audience

The main area of use for this profile is all areas where concrete formwork operations are carried out.

Sector	Area of Use	Target Audience
Construction and Contracting	In the formwork corners of columns, shear walls, beams, foundation footings, and retaining walls.	Construction Companies, Contractors, Formwork Masters.
Infrastructure Projects	Reinforced concrete constructions in places such as bridge piers, culverts, and tunnel entrances.	Road and Infrastructure Project Managers.
Precast Structures	In the corner finishes of reinforced concrete precast elements (panels, columns) used in factories and warehouses.	Precast Production Facilities.
Architectural Applications	In reinforced concrete facade and interior details with high aesthetic expectations.	Architectural Offices and Detail Applicators.

User Information and Advantages

Ease of Installation: The "lugged" design offers craftsmen the ability to nail or staple the profile to the formwork quickly and accurately, which shortens labor time.

Repeated Use: Thanks to its Rigid PVC structure, it is not damaged after the formwork is removed (demolding) and can be reused in many projects.

Cost-Effectiveness: By preventing concrete slurry leakage, it eliminates the need for additional repairs (retouching) at the corners after the formwork is removed, saving time and material.

This product is an indispensable formwork accessory for achieving speed, efficiency, and quality surface finish on construction sites.
