Thanks to the extensive collection of plates, you can train both compound and isolation exercises for a holistic routine.
Weight plate pairs include increments of 25kg, 15kg, 10kg, 5kg, 2.5kg and 1.25kg plates. This selection works great for advanced lifters focusing on heavy compound movements such as squats and bench presses. The inclusion of 25kg plates makes for significant weight increments, essential for progressive overload (gradually increasing the intensity to avoid plateau) in strength training.
The weight plates come in pairs of 25kg, 20kg, 15kg, 10kg, 5kg, 2.5kg, and 1.25kg plates. This is a great set for professional athletes and gyms requiring a wide range of weight plates for various training programmes. From intense low-rep, heavy-weight strength training to low-weight, high-rep endurance training, these plates will suit and support any form of weight training.
Factory Weights offers optional add-ons to enhance the flexibility of your training setup. Additional cast iron plates are available in various sizes to add extra intensity to your workout. You can also choose to include an adjustable bench, and a squat stand to firmly support your bars and plates.
While we include standard spring collars, you can choose to upgrade your collars with our barbell collars available in different colours to customise your gear.

Choosing a barbell cast iron weight set over vinyl weights or standard weight plates such as cement-filled plastic weights gives you better durability and reliability.
Cast iron plates are more resistant to damage, unlike vinyl-coated plates that tend to crack over time and usage. This makes cast iron weight plates ideal for long-term use in heavy lifting, perfect for commercial gyms or robust personal gyms.
Olympic bars can withstand higher total weight than their standard counterparts. Olympic bars are also longer and wider and have larger bar ends over bars found in standard weight sets.
