Pocz\u0105tkowo wytwarzano elementy kute na potrzeby lokalnego rolnictwa. Od 1928 roku rozpocz\u0119to produkcj\u0119 pierwszych wyrob\u00f3w dla sektora grzewczego. W 1940 roku z powodzeniem wyprodukowano pierwsze kolana rurowe.<br\/>W 1957 roku powsta\u0142 nowy zak\u0142ad produkcyjny w miejscowo\u015bci Lohne. Od 1970 roku prowadzono pierwsze pr\u00f3by w zakresie produkcji grubo\u015bciennych kolan rurowych. W 1987 roku firma Siekmann zosta\u0142a ponownie za\u0142o\u017cona w lokalizacji B\u00fcnde.<br\/>Od 1992 roku produkcja zosta\u0142a ukierunkowana na specjalne kolana rurowe o du\u017cych grubo\u015bciach \u015bcianek. W tym celu opracowano nowe technologie produkcji, kt\u00f3re w znacznym stopniu przyczyni\u0142y si\u0119 do dzisiejszego sukcesu firmy. W kolejnych latach zakupiono nowe dzia\u0142ki oraz wybudowano now\u0105 hal\u0119 produkcyjn\u0105.          <\/p>\n\n\n\n<p class=\"has-text-align-center has-large-font-size\"><\/p>\n<\/div><\/div>\n\n<h2 class=\"wp-block-heading\" id=\"referenzen\">Referencje<\/h2>\n\n<ul class=\"wp-block-list\">\n<li>Total S.A.<\/li>\n\n\n\n<li>Siemens<\/li>\n\n\n\n<li>Hitachi Power<\/li>\n\n\n\n<li>Alstom Power<\/li>\n\n\n\n<li>Exxon Mobil Production<\/li>\n\n\n\n<li>Buhlmann Rohr-Fittings- Stahlhandel<\/li>\n\n\n\n<li>STAROFIT Klose GmbH &amp; Co.
