Is the Interjoint technology suitable to build inclined roofs?

Yes. Based on our proprietary technology, we have also designed the Bracket X which is inclined at 9.5 degrees for sloped roofs and is fully compatible with other Interjoint components.

Are there Interjoint connectors for steel joists?

Not yet. For the moment we are selling the Interjoint connectors for framing corners (columns and main beams). However, the development of new products is a key activity at the company, so we are already working with Interjoint connectors for joists including the 1″x2″ hollow square tube.

What are the specs of the steel tubes that are compatible with the Interjoint connectors?

The version that is listed on sale is compatible with galvanized steel tubes 3″x3″ (hollow square tubes), gauge 16 or gauge 14.

Is it possible to disconnect the Interjoint connectors once they are interlocked?

The Interjoint connectors have been designed to lock the column terminals with the beam brackets so they don’t get out. However, they can be uninstalled using special tools.

What kind of structures can be built with the Interjoint connectors?

The Interjoint technology was designed for the assembly of lightweight steel framing, specifically galvanized steelwork. The technology is mainly suitable to assemble patio and terrace structures and pergolas. We mostly recommend its use for temporary steel structures.

Is the Interjoint technology suitable to assemble wooden pergolas and lumber structures?

Our proprietary technology can be easily adapted to interlock with wooden components. However, the adapted version is not listed for sale yet. Customers interested in this option must request it via email at or by filling our Contact form, click here.

Can the Interjoint technology be used to build large steel structures?

The Interjoint technology was originally engineered to assemble structural steel components such as WF beams and HSS columns. Our utility patent (US 11,230,838 B1) foresees the assembly of multi-story buildings located in seismic zones. Once the patented Structural Steel Plug for Bi-Axial Moment Connections achieves the proper certification, we will start delivering the building technology for the assembly of high-rise buildings and similar steelwork onsite.

Is the Interjoint technology suitable for modular construction?

The Interjoint concept is originally based on the benefits obtained from the prefabrication, standardization, and modularity. These connectors are more than ideal to build modular steel frames and assemble them on site.

Where is Zero Damage LLC shipping the product?

Presently, we are manufacturing and shipping our products in Puerto Rico, USA. We are scaling our business to start shipping the Interjoint technology and the Interjoint Building Kits in the US Virgin Islands, the Dominican Republic, and the US continental states.

What is included with the building kits?

The kits we sell include all the components of the construction system necessary to build the structure as shown. However, some components availability such as galvalume, sunscreens and glass are subjected to our supplier’s stock. Normally, we sell all the galvanized steel components and Interjoint connectors and the customer acquires other components separately.

What are the warranty terms and conditions?

Zero Damage guarantees the interlocking performance of the Interjoint steel connectors (Interjoint Terminals and Interjoint Brackets) until the product is fully installed. If the Interjoint Terminal or the Interjoint Bracket is broken or malfunctional when delivered, the company replaces the Interjoint steel component without charge. However, if some of the Interjoint connector components break during the installation due to the customer mishandling, the company is not responsible for that and could charge for the new component replacement and its shipping.

For the steel and wooden kits, Zero Damage guarantees the quality and performance of the kit components until delivered to the customer. In addition, Zero Damage allows a fifteen (15) calendar days period, starting when the kit is delivered, for claims and complaints. If Zero Damage manages the installation of the kit, then the fifteen-days period will start when the installation is completed. During the fifteen-days period, Zero Damage could partially or fully replace the kit or any of its components without charge if it was concluded that it was delivered with manufacturing defects and not because of the customer mishandling of the product. Zero Damage does not guarantee nor replace for free any steel, wooden or any other kit component beyond the fifteen-days period as previously defined for any damage including rust, paint damage, scratches, or the natural material deterioration.

If the installation is not managed by Zero Damage, the company will not be responsible for any damage caused to the kit components during the installation or due to the handling of the kit before and/or after the installation.

Do the Interjoint connectors withstand earthquakes and storm wind loads?

Though this technology has been engineered for the assembly of seismic-resistant steel moment frames, the technology is still going through the certification process. Hence, we do not recommend to use the Interjoint connectors alone to build permanent structures that would be exposed to earthquake forces or atypical (storm, hurricane) wind load. Other code-compliant and redundant building components must be employed in addition to the Interjoint connectors to protect the built structure during a storm or a hurricane, and/or an earthquake.
