Risk-Based Specification

Security Packages by Site Risk Tier

Security spending should follow exposure, not habit. A storage yard ladder climbed twice a month by one technician needs a different answer than a substation fence line that children test every weekend. The tier table below packages our factory-direct hardware into escalating bundles, so you specify once for a whole site instead of deciding gate by gate. Every tier ships retrofit-ready with DoC and certification to OSHA 1910.28 and EN ISO 14122-4, and lock hardware within one order can be keyed alike so a single key serves the site.

Coastal or chemical locations move the whole package to SS304 (≈1.8x) or SS316 (≈2.5x) for corrosion duty, with quotes back in 24 hours.

Security Gate Part File — Codes, Ratings, Service Triggers

Anti-Intruder Gates, Filed Like the Security Assets They Are

A security gate deters two threats at once — the fall at the cage entry and the intruder at the fence line. Order it by code, log it in the security register, and inspect it on the triggers below.

Ordering CodePartSpecEx-Works Band
DT-SG1-LKLockable security gateΦ700 cage entry, self-closing leaf, cylinder lockupper $60–180 band plus lock option
DT-SG2-HDHeavy-duty leaf variantreinforced frame for vandal-prone sitesquoted with the site survey details
DT-SG3-KAKeyed-alike security setone key across the perimeter gatesquoted per set
DT-SG4-SSSS304 security buildcoastal and chemical-site alloy≈ 1.8× the HDG price

Security and service triggers

  • Tamper evidence walk-round — lever marks at the frame, stretched hinge bolts or a scarred cylinder are intrusion attempts; replace the unit and re-key the set on discovery
  • Lock cylinder rotation — when keys change hands or a holder leaves, re-key the DT-SG3-KA set; security that outlives its key holders is not security
  • Self-closing check at every patrol — the security gate still has to satisfy the safety inspector; a leaf that no longer closes on its own is a compliance finding first, a security one second
  • Coating integrity — HDG 85–100 μm per ISO 1461 resists weather, not crowbars; re-dip or replace any gate scarred in a forcing attempt
  • Register review quarterly — codes, key holders and inspection dates in one row per gate keeps the security audit to a clipboard walk

Security Features, Risk Results

Five Things a Factory Security Gate Removes From Your Risk Register

Each row translates a factory feature into the risk line it closes — for the safety officer and the security manager alike.

Cage Ladder Security Gate FAQ

How do I choose keyed or combination locks?
Keyed locks suit single-owner access; combination locks suit shared teams where keys are often lost. Both retrofit to existing ladders.
Can the security gate retrofit my existing ladder?
Yes — the security gate is retrofit ready and fits standard cage ladder openings.
Does a keyed security gate ship with its own certification?
Yes — DoC and certification to OSHA 1910.28 & EN ISO 14122-4 ship with every gate.
Is there a discount for volume orders?
Yes — factory-direct volume pricing applies on multi-gate orders, quoted within 24 hours.
Does a security gate also serve as the required safety gate?
Yes. A security gate delivers the same self-closing protection at the opening while adding access control — order it as the single gate per opening rather than stacking two products on one ladderway.
Can we change the combination code periodically?
Yes — combination locks can be recoded in the field using the supplied instructions, so codes rotate when crews change. Keyed cylinders are instead reordered to your original specification whenever keys must be replaced.
Is one security gate enough for a school or substation?
For high-risk sites, layer instead of relying on one barrier: a keyed security gate at the cage opening plus an anti-climb guard over the lower rungs, both keyed alike — controlling the opening and the base of the climb.
What does a security gate cost versus a plain safety gate?
Both sit in the $60–180 ex-works band, with lock hardware as the differentiator. SS304 runs about 1.8x and SS316 about 2.5x for corrosive sites, and consolidated sea freight adds $280–550 per six-meter ladder.
