Factory Controlled Quality – Built into every TIGER System Tymetal Corp. has been manufacturing aluminum gates and operators for over 20 years and has the experience and expertise to guarantee a quality gate system. From the welding process that is certified per AWS D.1.2 Structural Welding Code to the welding jigs that are aligned with lasers – Tymetal quality is unsurpassed. From individual welders who have to pass stringent qualification tests to the aluminum extrusions of exact tempers that are specifically designed for strength and appearance – the Tymetal gate system is the best. Gate systems are what Tymetal Corp. does and this product focus is evident in the quality of the system produced. Why rely on a gate that is fabricated on the job site or from a “me too” manufacturer without certified processes, materials and proven know how?

3. Gap protectors shall be provided and installed, compliant with ASTM F 2200-05.
F. Diagonal Bracing:
1. Diagonal “X” bracing of 3/16″ (5mm) minimum diameter stainless steel aircraft cable shall be installed throughout the entire gate frame.
G. The gate shall be completed by installation of approved filler as specified.
1. Ornamental Picket: Picket sizes shall be 1” (25mm) square. Pickets may extend through only the clear opening portion or through the entire length of the gate as required. If a motorized gate operator is to be applied to the gate and the specified picket spacing allows for openings in the gate frame that exceed 2¼” (57mm), a secondary gate filler shall be secured at each end of the gate frame and tied at each 1” x 2” (25mm x 51mm) or 2” x 2” (51mm x 51mm) vertical member. The secondary gate filler shall extend to a minimum height of 72” (1.2m) above grade and shall be sized to prevent a 2¼” (57mm) diameter sphere from passing through openings anywhere along the length of the gate frame, and in that portion of the adjacent fence that the gate covers in the open position.
H. Posts (by others):
1. Double sets of support posts shall be minimum 4″ O.D. (102mm) round Schedule 40 or 4” x 4” x 3/16” wall square steel tubing, grade 500. Gate posts shall be galvanized or coated and supported in concrete footings as specified by the design team.
I. Finish:
1. Gate to be mill finish aluminum or color coated with polyester powder as specified. If powder coated, the gate (including track member) and all accessories shall be pretreated chemically by sand blasting or other acceptable method to ensure proper coating adherence.
J. Gate Lock:
1. Gate system shall be furnished with a secure gate catcher. The catcher shall prevent the gate panel from being pried open while the gate is in the closed and locked position.
2. Gate system shall be furnished with an electro-mechanical lock. Lock shall be supplied with status indication and with a six tumbler mechanical lock. All gates shall be keyed alike. Lock requires additional 115V power supplied by others.
2.07 WARRANTY:
A. The cantilever slide gate and operator system shall be warranted by the manufacturer against manufacturing defects for a period of (3) three years from date of sale. The truck assembly shall be warranted against manufacturing defects by the manufacturer for a period of (5) five years from date of sale.
2.08 CONTROLS:
A. UL listed Class III or IV operator:
1. Class III: Momentary contact control with non-contact sensor and alarm. Non-contact sensors shall provide external primary entrapment protection system and must be installed for both close and open gate directions. When this equipment is installed, momentary contact on the pushbutton control will start or stop gate movement. The secondary entrapment device shall be the inherent audio alarm. The built-in auto-close timer may be used to automatically close the gate from a full open position after a user set time (from 2-60 seconds).
B. For Class III operation with Momentary Contact Control – Two Albano IR-55 Photo-beams are to be provided with the operator as devices to provide primary entrapment protection under the UL 325 guidelines. The provision of the above photo-beams does not alleviate the installing contractor from the responsibility of identifying and providing protection from safety hazards (entrapment zones) under UL 325 standards for Class III or IV installations. The secondary entrapment protection device provided shall be the inherent audio alarm.
C. The installing contractor shall be responsible to ensure that appropriate external primary entrapment safety devices be installed for the specific site conditions to protect against all potential entrapment zones. Proper operation of these safety devices shall be verified and training as to the operation and maintenance of these devices for the users and owners shall be documented.
2.09 CONTROLS FOR ELECTRICALLY OPERATED CANTILEVER SLIDING GATES (UL Class III or IV):
A. Select and specify access control devices for this specification section. Operator compatible with most industry accessories.

B. The system shall be operated for a sufficient period of time to determine that the system is in proper working order.
C. Test and Explain Safety Features:
1. Each system feature and device is a separate component of the gate system.
2. Read and follow all instructions for each component.
3. Ensure that all instructions for mechanical components, safety devices and the gate operator are available for everyone who will be using the gate system.
4. The warning signs shipped with the gate operator must be installed in prominent position on both sides of the gate.
D. Ensure the owner is clear with regard to the safety points concerning the basic operational guidelines of the safety features of the gate operator system. These safety points are listed in the operator manual and must be read prior to system use.
