Steel Windows & Doors FAQs

Q: What are the differences between hot rolled and cold rolled steel?

A: Hot rolled steel windows and doors are made from solid steel sections hot rolled from billet steel into shapes designed for frames and ventilators. Cold rolled steel windows and doors are made from hollow steel sections mechanically formed from flat sheets into specially designed profiles.

Q: Do you use recycled materials to make steel windows and doors?

A: Yes. Hot rolled steel windows and doors could be manufactured from steel sections made of recycled steel.

Q: Is it true that aluminum glazing beads react poorly to steel?

A: No. Paint finishes prevent any corrosive interaction between dissimilar metals.

Q: Are steel windows thermally efficient?

A: Yes. Steel has five times the thermal resistance of aluminum and allows larger glass areas for improved U-values.

Q: Are thermal breaks available?

A: Yes, steel windows and doors are offered with or without thermal breaks.

Q: What are the U-values?

A: A U-value (or thermal transmittance) measures the rate of heat loss or gain through building elements. U-values vary by glass type, thickness, and configuration. Consult Steelguard for project-specific performance data.

Q: What is condensation resistance (CR)?

A: Condensation resistance (CR) is a measure of how well a window, door, or skylight resists water buildup on its interior surface. CR varies based on size, configuration, and glass type.

Q: What types of glass can be used?

A: Glass thicknesses from 3mm to 50mm can be accommodated, including laminated, leaded, and insulated glass.

Q: How are steel windows glazed?

A: Using glazing tape, wedges, setting blocks, custom beads, and sealant.

Q: How easy is glass replacement?

A: Glazing beads allow easy removal and replacement.

Q: Why ship without glass?

A: Field glazing is safer and more practical for large custom units.

Q: How does steel compare to aluminum, wood, or vinyl?

A: Steel offers superior strength, longevity, and structural performance compared to aluminum, wood, or vinyl. Its exceptional tensile strength allows for significantly slimmer profiles and larger expanses of glass without compromising integrity. Unlike wood, steel will not warp, crack, or rot over time, and unlike vinyl, it does not degrade from UV exposure or temperature fluctuations.

Q: Can steel windows meet fall prevention requirements?

A: Yes. Windows can be restricted to meet code and released for cleaning.
