Clear all your doubts!

What are the most commonly used types of steel in the manufacture of metal roofing sheets?+

• Galvalume steel: A mix of aluminum, zinc, and silicon, known for its excellent corrosion resistance and durability.

• Galvanized steel: Coated with zinc, offering good corrosion resistance and an economical option.

• Pre-painted steels: Undergo a painting process that enhances durability and improves the aesthetic appearance of the sheets.

• Aluminum: Lightweight and corrosion-resistant, it is often used in metal roofing sheets, especially in corrosive environments.

Among these, natural galvalume steel and its pre-painted version are the most commonly used.

What is the difference between galvalume steel and galvanized steel?+

Galvanized steel is coated with zinc, while galvalume steel is coated with a mix of aluminum, zinc, and silicon (ASTM A792 standard). Galvalume is more resistant to corrosion and oxidation, provides better thermal insulation, and has a longer lifespan. It is more suitable for applications requiring durability, but galvanized steel is also widely used due to its lower cost.

What types of roofing profiles exist?+

There are various metal roofing profiles on the market. The two most common are corrugated metal roofing sheets and trapezoidal metal roofing sheets.

• Corrugated sheet: Features sinusoidal waves, allowing for better water drainage, structural resistance, and a pleasing aesthetic. It is used in homes, rural areas, warehouses, gyms, and more, especially in arched roofs, as it can be curved without creasing.

• Trapezoidal sheet: Formed by trapezoidal-shaped waves. This model offers a variety of trapezoid heights, each suitable for specific roofing and styles:

   • TR-40: Commonly used in roofing and side enclosures of warehouses, commercial establishments, and facades.

   • TR-35: Has fewer undulations and the largest useful width on the market, at 1,050 cm. Widely applied in side enclosures.

   • TR-25: Easy to handle, can be used for both flat roofing and side enclosures, as well as in facade architecture.

What is a thermoacoustic roofing sheet? And a simple roofing sheet?+

• Thermoacoustic roofing sheet: Also known as a sandwich panel, it is made of steel with an insulating material (expanded polystyrene or polyurethane) inserted between two metal sheets. It provides better thermal and acoustic insulation. Used to create and seal walls and facades. Advantages include energy savings, easy maintenance, and no need for additional ceiling coverings.

• Simple roofing sheet: Composed of a single sheet, it still offers high resistance and quality. Considered a more economical option.

What is the thickness of the roofing sheets?+

Sheets produced within standards have a typical thickness ranging from 0.45 mm to 0.65 mm.

How much does a meter of roofing sheet weigh?+

The weight per meter varies according to sheet thickness, material used, and profile. The most common sheet, with a thickness of 0.45 mm, weighs between 2.5 kg and 4.5 kg per square meter.

What are pre-painted and post-painted sheets? What is the difference between them?+

• Pre-painted sheets: Made from steel coils that are painted before being turned into sheets. The process is called "coil coating" and involves:

  • Pre-treatment (sheet cleaning)

  • Application of a sealant (corrosion protection)

  • Controlled primer application

  • Uniform paint layers (top coat)

Advantages: Practicality, durability, superior aesthetics, and resistance.

• Post-painted sheets: Painted after they have been manufactured and shaped. The process includes:

  o Cleaning and preparation of the sheet

  o Electrostatic painting with polyester powder

  o Application of the final paint layer and drying

Advantages: Color flexibility, customization after manufacturing, practicality for small-scale projects.

What is the standard coil width?+

Coils used for sheet production typically have a standard width of 1,200 mm. After forming, the sheet will have a reduced width, depending on the produced profile.

How can coils be handled?+

Coil and sheet handling can be done in various ways, depending on the available structure and company needs. Options include:

• Overhead cranes: Ideal for properly structured warehouses.

• Gantry cranes: An efficient alternative for in-factory handling.

• Forklifts: Useful for quick and precise maneuvers.

• Truck-mounted cranes: A good option for customers who have not yet invested in overhead or gantry cranes.

What is NR-12, and what happens if the machine does not comply?+

NR-12 is a regulation from the Ministry of Labor that establishes safety procedures for the transportation, installation, operation, and maintenance of machines. It aims to protect operators from accidents. If a company does not comply with the regulation, it assumes risks and responsibilities for accidents and may be fined, have production halted, or be shut down.

Where can I buy steel coils?+

Steel coils can be found at major steel mills. At Esquadros, we provide a list of suppliers during the machine negotiation process to facilitate the purchasing process.

What should be considered when choosing a supplier?+

More important than buying a machine is buying the right machine! To ensure a safe and successful purchase, take the following measures:

• Ensure that the machine is technically suitable for your application: Analyze the technical specifications, compare options, and leverage the knowledge of sales and engineering teams.

• Visit the manufacturer’s facilities: Get to know the manufacturing processes and quality standards.

• Visit machines in operation at other companies: Talk to customers about their experience.

• Prefer machines with higher automation: They offer greater safety, productivity, and reduced operational costs. Avoid outdated technologies.

• Evaluate after-sales support (parts and services): Ensure efficient and effective support.

• Pay attention to delivery times and commitments.

• Check the manufacturer’s financial stability: Especially before making any upfront payments, to avoid future issues or losses.

What are the advantages of having your own metal roofing production?+

• High machine productivity eliminates the need for ready-made sheet stock

• No minimum order quantity

• Immediate delivery

• Custom length sheets

• Internal quality control

What is the ideal decoiler?+

Choose the decoiler based on your production demand. Esquadros Decoilers offer productivity options and cater to customers investing in automation to increase production at a lower cost. The Esquadros Pro/Premium Decoiler has a capacity of up to 15 tons, while the Essential model supports up to 10 tons.

How many meters per minute does a roofing machine produce?+

• Esquadros Essential Machine: 15 m/min

• Esquadros PRO Machine: 15-25 m/min

• Esquadros Premium Machine: 25-60 m/min

The nominal speed is reached after the initial inertia, and the cycle is only interrupted during deceleration for the guillotine cut.

Can a single machine produce two roofing profiles?+

Esquadros offers the Dual Roofing Machine, which allows for two different roofing profiles.

What space is needed for installing a roofing machine?+

The space required for installing a roofing machine varies depending on the profile being produced and the selected decoiler.

What is the initial investment amount?+
