Beware of Rust and Corrosion of Cheap Metal Building Fasteners

Iconic drawing of a metal building with quality screws.Cheap screws rust.  Rust spreads to the steel panels, streaking the steel panels with unsightly rust discoloration.

However, rust is much more than a cosmetic problem.

Once rust forms, it spreads.  Corrosion may eventually cause serious structural problems in metal buildings.

In addition, rusty metal building fasteners with cheap washers leak.  Leaking buildings create a mess, soaking insulation and dripping onto the building’s contents.

Cheap Metal Building Screws are even Unhealthy

Rusty surfaces easily trap tetanus spores.  Once the bacterial spores enter a body, they produce tetanospasmin, one of the deadliest neurotoxins known to medical science.

Thanks to vaccinations, tetanus (also known as lockjaw) is very rare in industrialized countries.  However, it is far more common in developing nations.

According to the Mayo Clinic, there is no cure for tetanus.

Steel Building Construction with RHINO’s Cast Zinc Aluminum Screws

RHINO steel buildings use only top-of-the-line steel building screws with high-grade washers for maximum leak and corrosion protection.  Our high-end screws and washers improve the value and the longevity of steel buildings.

All RHINO metal building construction kits include cast zinc aluminum fasteners for all steel panel sheathing.  Cast screws resist the shank destruction and head failure common with capped metal building hardware.

Die-cast zinc aluminum screws offer high torsional strength.  The self-drilling tip also provides greater efficiency, speeding up installation.

These RHINO fasteners carry a lifetime warranty against red rust corrosion on the zinc head.

RHINO also supplies metal building screws with heads that match the color of the steel panels selected, for a more beautiful, professional appearance.

Strong and abrasive-resistant, EPDM washers weather the years extremely well.  EPDM washers withstand heat extremes, ozone deterioration, and ultraviolet rays.

EPDM sealing washers ensure a long-lasting waterproof seal even in the harshest weather conditions.


Superior metal building fasteners are just one part of the quality you can expect with a RHINO steel building kit.
