Looking for a heavy-duty outdoor pressure gate (big dogs)

Hi everyone! I’m looking for an outdoor pressure-mounted gate that’s weatherproof and heavy-duty and I’m hoping for some recommendations.

I have an outdoor patio but I’m renting so drilling into brick/concrete isn’t an option. I also have a 80 lb dog and a Rottweiler puppy, so I need something that won’t budge or topple if they lean on it or test it. I’m not planning to leave them out there unsupervised, but I still want peace of mind that it’s secure and won’t shift or fall.

The best option I’ve found so far is the NMN Designs Libro Metal Outdoor Dog Gate w/ Door (28.5"–61.5" extra wide, modern 32" tall, pressure-mounted). It seems like one of the only gates actually designed for outdoor use with a heavy duty weather-resistant build but it’s expensive (about $400 even with a discount) so I’m trying to see if there are other solid alternatives before committing.

Has anyone used this gate specifically? Or found something similar that actually holds up with big/strong dogs?

Would really appreciate any recommendations or experiences — especially from people with larger breeds!
