Materiais, acabamentos e fabricação personalizada

ESANG anchoring systems can be supplied or manufactured according to project requirements, including anchor type, diameter, length, thread detail, washer and nut selection, base plate compatibility, material grade, surface finish, and packaging requirements.

Material ou acabamentoUso típicoNotas
Aço inoxidável 304Interior handrail, railing, and bracket anchoring in dry environmentsA common option for many indoor installations where corrosion exposure is limited.
Aço inoxidável 316Outdoor, coastal, poolside, humid, and higher-corrosion environmentsNormalmente, é preferível quando é necessária uma melhor resistência à corrosão.
Aço inoxidável 316LProjects requiring low-carbon stainless steel or more demanding corrosion performanceSuitable when the specification calls for 316L material.
Brushed or passivated finish where specifiedArchitectural or corrosion-focused stainless steel hardware projectsFinish and treatment should be confirmed according to the project requirement.

For non-standard anchoring projects, customers can provide drawings, anchor dimensions, substrate details, base plate layouts, thread requirements, material grade, finish requirements, and installation conditions. ESANG can review the requirements and manufacture anchoring hardware to match the project specification where feasible.

Compatibility with Railing and Handrail Hardware

Anchoring systems should be selected together with the hardware they support. The same anchor may not be suitable for every wall bracket, post base plate, glass spigot, or cable railing component.

Personalização de acordo com os requisitos do projeto

Many anchoring projects are customized according to substrate condition, base plate design, post size, bracket layout, corrosion exposure, and installation method. ESANG can support custom masonry anchor hardware, expansion anchor hardware, chemical anchor components, heavy duty anchor bolts, threaded rods, washers, nuts, and related stainless steel fastening parts.

When a project has standard-oriented requirements related to guardrail height, handrail support, base plate fixing, material grade, corrosion resistance, or load-related design requirements, customers should provide the required drawings and specifications. ESANG can manufacture anchoring hardware to match those provided details, while final compliance depends on the complete installed system, substrate condition, structural design, installation method, and applicable local code.

Considerações sobre instalação e projeto

Anchoring systems should be reviewed before drilling, base plate fabrication, or site installation. Anchor selection is closely tied to substrate strength, edge distance, embedment, hole preparation, and the component being fixed.

  • Substrate type and substrate condition
  • Anchor type: masonry, expansion, chemical, or heavy duty bolt
  • Anchor diameter, length, thread detail, and embedment depth
  • Hole diameter, hole depth, drilling method, and cleaning procedure
  • Base plate, wall bracket, glass spigot, or post hardware layout
  • Edge distance, anchor spacing, and installation access
  • Tipo de material adequado para ambientes internos, externos, litorâneos ou à beira da piscina
  • Código de construção local e requisitos de especificação do projeto

For post-installed anchors in concrete, project teams may need to review evaluation criteria, manufacturer installation instructions, and local code requirements. The ICC-ES approved acceptance criteria search is one reference point for U.S. evaluation criteria related to post-installed anchors. Final anchor selection and installation approval should be confirmed by the project designer, engineer, contractor, or local authority.
