What Is a Support Sheet / Reinforcement Sheet?
A Support Sheet – also known as Reinforcement Sheet, PVC Reinforcement Sheet, Steel Insert for uPVC Profiles or Internal Reinforcement Sheet – is a metal strip placed inside the reinforcement chamber of PVC window and door profiles. It increases:
- Bending resistance and stiffness
- Screw-holding capacity for hinges, locks and fittings
- Dimensional stability under thermal expansion
- Load-bearing capacity under glass and wind loads
- Overall lifespan of uPVC and PVC frame systems
These inserts are typically manufactured from galvanized steel, cold-rolled mild steel or hot-dip galvanized steel, in compliance with EN and ASTM standards. HL Metal offers multiple geometries (U, C, L, Z, omega and flat designs) to match your profile chambers.

Galvanized steel plates are coated with zinc to prevent corrosion, which is commonly seen in metals. The galvanized material can be applied effectively to almost any wet or humid surface, making it a preferred choice in such environments. Today, galvanized steel plates are widely used on moist and damp floors due to their high protective performance.
The main component of galvanized plates, zinc, provides a strong barrier against various negative environmental effects, preventing these from damaging the surface of the sheet metal. As a result, galvanized plates help extend the durability and integrity of metal structures and components.
Galvanized steel plates are commonly used across many industrial sectors because of their ease of use and practical advantages. They are especially preferred in manufacturing processes to increase the resistance and longevity of the final products.
In iron and steel production, wet surfaces pose a significant problem. Galvanization helps eliminate this issue by protecting the metal from moisture-induced damage, especially rust and corrosion. This is why galvanized sheets are widely used in the production of goods that are exposed to moisture or humidity.
At HL Metal Iron & Steel, we offer top-quality and competitively priced galvanized steel plates to meet your business needs. Our expert team is ready to assist you with detailed information and personalized product solutions.
Premium Quality Galvanized Steel Products for Industrial Applications
Galvanized steel is one of the most widely used materials in modern construction, infrastructure, and manufacturing industries due to its exceptional corrosion resistance, durability, and cost-effectiveness. At HL Metal, we offer a broad range of galvanized products, including sheets, coils, tubes, and profiles designed to meet the diverse needs of our clients across Europe, the Middle East, and North Africa.
What is Galvanized Steel?
Galvanized steel refers to steel that has been coated with a layer of zinc to protect it from corrosion. The most common process is hot-dip galvanization, where the steel is submerged in molten zinc, creating a strong and uniform protective layer. This zinc barrier significantly extends the product’s service life, especially in harsh outdoor environments.
Our Galvanized Product Range
We supply a wide variety of galvanized items, such as:
Galvanized Sheets (plain, patterned, or corrugated)
Galvanized Structural Profiles (angles, channels, hollow sections)
Cold-Formed Galvanized Profiles for construction and framing systems
Each product is available in various thicknesses, widths, and zinc coating levels (Z100 – Z275), tailored to your project requirements.
