About dell-core edge protection


With more than 15 years of Experience in the high-rise construction industry, Dell-Core Edge Protection takes immense pride in providing the highest quality of service to our valued clients.

Dell-Core Edge Protection is a division of The Hardrock Group of Companies. With over 800 employees and 45 years of experience, Hardrock is one of the largest concrete forming companies in Canada. Our vast experience includes providing leading edge protection for large scale, multi-million dollar concrete forming projects, including skyscrapers, hospitals, subway stations and 60+ storey condominiums.

Dell-Core’s belief in providing the high-rise construction industry with the safest and most efficient edge protection products comes from years of real-world experience and feedback from concrete formwork crews. We have consistently observed that providing confidence to workers with a safe and quickly installed edge protection system significantly increased their productivity on site.

Our continued passion for safety on the job site, particularly the formwork industry, motivated Dell-Core Edge Protection to purchase the patents and the exclusive manufacturing rights for all of the Speed Edge products.

Falls account for over a third of casualties in the construction industry each year. To protect your workers, guardrails are your first and most effective line of defence over any other method of fall protection.

We manufacture our own line of custom edge protection solutions that have been recognized industry-wide for their simplicity, quality and innovation. That’s why North America’s leading firms consistently choose Dell-Core products.

I have been using the Edge Protection System from Dell-Core since 2012, and I would like to comment in my 38 years of running projects this system is by far the safest system used in the industry, it is light, easy to install/dismantle which in my mind makes it very efficient.

The service from Dell-Core has always been fast, clean and organized on pallets just the way we like to see it, I strongly support and recommend Dell-Core for your edge protection of choice.

ITC Residential BC II Inc

I had used the Dell-Core edge protection in Edmonton with good success. I am now working on a 56-storey tower in Vancouver and am using the Dell-Core Edge Protection on this job site. It is easy to use, stronger than wood cattle guard and a big-time saver, which equates to dollars being saved.

The service from Dell-Core has been very good on the sites I have run. The equipment is in great shape. I would not hesitate to give Dell-Core a high rating on both their service and equipment.

Elite Formwork has used the Dell-Core perimeter fencing for all our high-rise projects since they entered into our market more than a decade ago.  The system has proved to be safe, cost effective and the customer service has been excellent over the years and we plan on continue using the same system for our future projects.

Eric Yam, Project Manager
Elite Formwork


We at Cemrock, have been working with Dylan and Dell-Core products for quite a few years now. We have found the system to be incredibly easy to use. It saves labour time and materials that would otherwise be discarded.  Once the workers have been instructed, they are very quick in setting the fencing up.  It is also much safer than traditional wooden hand rails and offers a nice visual safety reference for quick inspection.

Dylan and the crew at Dell-Core always deliver on time and have done “out of hours” work to ensure the fencing gets to sites on time.

We are very pleased to have Dell-Core on all our towers to date and are excited to continue to work with them in the future.

Smart Safety Solutions Inc.

This letter is to express just how the Dell-Core Edge Protection and debris netting systems have set the bench mark for perimeter building safety in the construction industry.

Now in my 25th year in construction safety management I have personally witnessed the transition from wooden guardrails to alternative methods of edge protection systems in Ontario. Smart Safety Solutions have been involved with the Dell-Core systems from they’re inception and can say with all confidence that there are no safer, faster and easier edge protection systems on the market.

Smart Safety currently manages full turn-key safety systems for a number of the largest, highly dedicated high rise builders in Ontario and all of these builders have selected Dell-Core as the only provider for perimeter protection and with very good reason. No other company provides a better quality product that includes the level of training, engineering, service and price.

When people’s lives are at the mercy of the most important method of fall and overhead protection on high rise projects why take a chance with inferior systems. In my professional opinion there are no other systems on the market today that provide the level of safety and security to builders.

Steve Heck, BASc. CRSP

The Speed Edge System is fast to install, easy to use and dismantle, but overall it’s the safest form of edge protection around. We will continue to use this system on all of our future projects.
