GuardShack Products – Limited Warranty Policy

GuardShack Products provides a limited warranty covering original manufacturing defects on all products. This warranty is intended to ensure that each enclosure meets our quality standards at the time of production and delivery.

Covered Under Warranty
The warranty applies to defects resulting from the manufacturing process, including but not limited to:

  • Construction-related issues (e.g., loose or broken welds)
  • Factory damage or dents
  • Incorrect dimensions or fabrication errors
  • Powder coating defects such as uneven coverage, de-bonding, or cracking

Not Covered Under Warranty
The following conditions are not covered under this warranty:

  • Environmental damage, including rust or corrosion on mild steel products
  • Damage caused by exposure to high humidity, coastal environments, or irrigation systems
  • Normal wear and tear over time
  • Damage in Transit or at Distributors Facility
  • Improper installation or customer modifications
  • Labor costs, including installation, removal, or replacement

Material Considerations
For installations in high-humidity regions, coastal environments, or areas exposed to regular water contact (such as sprinkler irrigation), stainless steel is the recommended material. Mild steel products are more susceptible to corrosion in these conditions.

As GuardShack Products distributes nationwide, we are not always aware of the final installation environment or specific application. It is the responsibility of the purchaser to select the appropriate material based on the intended use and conditions.

Warranty Process
To determine warranty eligibility, products must be returned to our facility for inspection. If a defect is confirmed to be covered under warranty, GuardShack Products will repair or replace the item at our discretion.

Due to the size and nature of our products, return shipping logistics may be evaluated on a case-by-case basis.

All claims must be submitted in writing within 30 days of discovery and within the applicable warranty period. The product must be returned to GuardShack’s facility in Phoenix, Arizona for evaluation.

All incidental expenses are the responsibility of the customer and are not covered under this warranty. If a defect is confirmed and determined to be covered under this Limited Warranty, GuardShack™ will cover the cost of return shipping.

If the issue is found not to be covered, all return shipping costs will be the responsibility of the customer.

Additional Notes
While additional coatings, such as primer combined with powder coating, can improve resistance to corrosion, no coating system can guarantee complete prevention of rust over time in harsh environments.

GuardShack Products is committed to delivering durable, high-quality enclosures and working with customers to reach fair and practical solutions when concerns arise.
