Why Steel?

Steel is famously strong, but there are additional advantages to bear in mind when you ask yourself, “Why Steel?”

Steel provides the best long-term value in the door and frame industry. It lasts longer, requires the fewest repairs, and is sturdier than other products. Steel’s natural strength also outperforms other materials in security, fire rating, sound reduction, vandal resistance, sanitation, and more. Hollow metal will outperform wood, aluminum, and fiberglass in demanding environments. Even when those other materials use special cores or other techniques, they are still unable to match the performance and longevity of hollow metal.

A beneficial byproduct of the strength and durability of hollow metal is the low total cost of ownership. Properly installed and maintained hollow metal doors often last 30 years or longer. As the years pass, steel doors can be inexpensively repaired in the field while softer, less durable wood and aluminum doors will have to be replaced.

Are you seduced by the so-called warmth of wood? Consider this: Today’s steel doors offer endless options for attractive appearances. Whether you are looking for a modern stainless steel appearance, a vibrant colored finish, or even a faux finish, steel’s versatility allows it to satisfy the aesthetic requirements of most projects. And don’t forget all those advantages of performance and longevity!

Steel doors and frames even help the environment, as steel is the most recycled material in North America.


Republic offers a complete line of standard and specialty hollow metal doors to fit your architectural needs. Republic doors are available in 20, 18, 16, & 14 gauge cold rolled and galvanealed steel. All doors come with a ¾” cell honeycomb core as standard, providing every door with a smoother, flatter, and stronger door. Republic honeycomb doors are available in a complete range of fire ratings (20 minute up to 3 hours) and are certified under both Underwriters Laboratories and Warnock Hersey/ITS. All doors are manufactured from stretcher level quality steel and are thoroughly cleaned and phosphatized inside and out offering excellent corrosion resistance and paint adhesion.


Republic offers a complete line of standard masonry (ME Series) and drywall (MH Series) frames to fit any of your architectural needs.  ME Series Universal Frames and MH Series Drywall Frames are constructed to conform to Steel Door Institute Standard ANSI A250.8-1998 (SDI-100).

ME Series shall be formed from 16, 14, or 12 gauge cold-rolled steel or galvanealed steel. MH Series Frames are formed from 16 or 14 gauge cold-rolled steel or galvanealed steel. (14 gage maximum height of 8’0″). Frames may be either knocked-down or have corners welded and ground smooth. All frames have aligning tabs and slots for secure and easy interlocking of jambs to head.

Frames are provided with 9/32″ DIA. silencer preparation, (3) per strike jamb and (2) per head for double openings for field application after finish painting. Frames for 1 3/4″ (44) doors have 9 gage steel universal hinge tap plates projection welded with provisions for 4 1/2″ (114) template type hinges and 14 gage steel strike reinforcement plate, extruded and formed to the equivalent of 10 gauge, projection welded with provision for a Universal ANSI A115.1 or ANSI A115.2 strike. Frames for 1 3/8″ (35) doors have 11 gage steel hinge reinforcement plates projection welded with provisions for 3 1/2″ (89) template type hinges and 14 gage steel strike reinforcement plate projection welded with provision for cylindrical ANSI A115.2 strike.


Republic pre-engineered steel frame components called “sticks” provide unlimited flexibility for opening systems.  Stick components are used to fabricate even the most complex entrance fronts, partitions and window wall designs.  Republic’s variety of jamb depths and sizes permits limitless design freedom.  Because stick assemblies are normally welded, they offer strength without seams showing between vertical and horizontal members.

These openings can be designed for any job requirement, fabricated from factory components and assembled and welded by factory trained Republic Distributors.  Since sticks are shipped as components and fabricated locally, shipping costs, job delays and design limitations are greatly reduced.

Republic sticks can be manufactured from 16, 14, or 12 gauge cold rolled or A60 galvanealed steel.  When sticks are used for door openings, they are prepared for all mortised and surface hardware.  Republic “stick” assemblies are constructed from three basic components:  Open Sections (perimeter members), Mullion sections (intermediate members) and Sill or Base sections (bottom members).
