Hollow metal door frames offer several advantages, including: – Strength: They are very strong and can support heavy doors. – Fire Rating: Many hollow metal frames are fire-rated and can withstand fire for a certain period of time. – Security: The solid construction resists forced entry. – Durability: They are resistant to warping, cracking, and damage from environmental factors. -Customization: Hollow metal frames can be easily modified on-site to fit various door sizes and requirements. Based on those we make the metal door frame rolling forming machine either has the fully automatic and half automatic metal door frame rolling machine. Metal door frame machine is a specialized piece of equipment used in the manufacturing process of hollow metal door frames. This machine is designed to shape or form steel strips or profiles into the desired shape of a door frame by a process called rolling. The main features and functions of a metal door frame rolling machine may include: 1. Rolling Process: The machine uses a series of rollers to bend and shape the steel strips into the U-shaped or C-shaped profile that makes up the door frame. 2. Adaptability: The machine is often adjustable to accommodate different sizes and types of door frames, allowing for versatility in production. 3. Automation: Modern machines can be automated to increase production efficiency and reduce labor costs. They can be programmed to produce frames of consistent size and shape.

A hollow metal door frame is a type of door frame constructed from steel that has been formed into a hollow profile. This design provides structural integrity and durability while keeping the weight of the frame relatively light. Hollow metal door frames are commonly used in commercial and industrial buildings due to their strength and resistance to wear and tear.
